The Probability Scale 17

Between Where every chance lies, with 0 on one side and 1 on the other.
Certain Sure to happen. On the scale it sits at 1.
Decimal 0.5 or 0.25: a way to write a chance with a point.
Even chance One half: as with heads on a fair coin.
Fraction A number such as 1/6: wanted outcomes over all outcomes.
Greater Bigger. The more likely event has this kind of number.
Half The chance of tails on a fair coin.
Impossible It cannot happen. On the scale it sits at 0.
Number line Draw one from 0 to 1 and mark where each event belongs.
Percent Out of 100. Chances run from 0 to 100 of these.
Probability A number from 0 to 1 that tells how likely an event is.
Ratio A comparison of two numbers, such as 1 to 5.
Scale A line from 0 to 1 on which chances are placed in order.
Unlikely Not expected to happen, though it could.
Value What a number is worth. A chance has one from 0 to 1.
Whole All of it. The chances of every outcome add up to this: 1.
Zero The number given to an event that cannot happen.

Words of Chance 17

Always Every time: how often a certain event happens.
Biased Said of a coin that lands on one side more often than the other.
Chance How likely something is. Also a word for luck.
Doubt The feeling of not being sure.
Fair Said of a coin whose two sides are equally likely to land up.
Guess An answer given without knowing for sure.
Likely Having a better than even chance of happening.
Luck Good or bad things that happen by chance.
Maybe Perhaps: it might happen and it might not.
Never At no time: how often an impossible event happens.
Odds A way to state a chance, as in 2 to 3 in favor.
Possible Able to happen, even if the chance is small.
Predict To say what you think will happen before it does.
Probable Likely to happen or to be true.
Random With no pattern, so nobody can tell what comes next.
Rarely Not often at all.
Sure Having no doubt at all.

Coins, Dice and Spinners 23

Bag Marbles are hidden in it so you cannot see which one you pick.
Card One of the 52 in a standard deck.
Coin Toss it and it lands on heads or tails.
Counter A small colored disk used in chance experiments.
Cube The shape of a standard die: six square faces.
Deck A full set of playing cards.
Dependent Said of two draws when the first changes the chances for the second.
Dice More than one die.
Die A small cube with 1 to 6 dots on its faces. One of a pair of dice.
Draw To pull a card or a marble without looking.
Face One flat side of a die.
Flip To toss a coin so it turns over in the air.
Heads The side of a coin that shows a face.
Land To come to rest: a coin can do this heads up.
Marble A small glass ball. Problems often ask you to pull one from a bag.
Pick To choose one thing from a group.
Replacement Putting the card back before the next draw.
Roll To throw a die and see which face lands up.
Section One slice of a spinner.
Shuffle To mix a deck of cards into a random order.
Spinner An arrow that turns on a circle cut into sections.
Tails The side of a coin opposite heads.
Toss To throw lightly, as you do a coin.

Outcomes and Events 23

Complement The event "not A": everything in the sample space that is outside A.
Compound Said of an event built from two or more simple events.
Conditional The kind of probability worked out given that another event has happened.
Disjoint Said of two sets with no member in common.
Element One member of a set.
Equally likely Having the same chance, like the six faces of a fair die.
Event A set of outcomes, such as rolling an even number.
Exclusive Mutually this: two events that cannot both happen at once.
Experiment A procedure you can repeat that has a known set of possible outcomes.
Failure In a trial with two outcomes, the one that is not a success.
Favorable Said of the outcomes you are hoping for.
Independent Said of two events when one does not change the chance of the other.
Intersection A and B: the set of outcomes that two events share.
Outcome One possible result of an experiment.
Overlap The part two circles of a Venn diagram share.
Result What you get when a trial is over.
Sample space The set of all possible outcomes: for a die, 1 to 6.
Subset A set whose members all belong to a larger set. An event is one.
Success In a trial with two outcomes, the one you count.
Total The count of all possible outcomes: the bottom of the fraction.
Trial One run of an experiment, such as one toss.
Union A or B: the set of everything that is in either event.
Venn diagram Overlapping circles that show how sets are related.

Counting the Outcomes 17

Arrangement Things put in a particular order.
Branch One line of a tree diagram.
Choice One of the options you can pick.
Column A line of a table that runs up and down.
Combination A selection in which the order does not matter.
Counting Finding how many. Its basic rule: a ways and b ways make a x b ways.
Factorial 4 x 3 x 2 x 1: a counting number times every counting number below it.
Grid A table of squares, such as 6 by 6 for two dice.
Order Which comes first, second and third.
Pair Two things together, such as a head and a tail.
Path One route along the branches of a tree diagram.
Permutation An arrangement in which the order matters.
Row A line of a table that runs across.
Systematic Done in a set order so that no outcome is missed.
Table Rows and columns that list every pair of outcomes.
Tally A mark made for each result as you count.
Tree diagram Branches that split at each step to show every outcome.

Experiments and Predictions 18

Average The total of the results divided by how many there are.
Data Facts and numbers that have been collected.
Empirical Based on the results of real trials, not on counting outcomes.
Expected This value is the long-run average of many repeats.
Frequency How many times a result was recorded.
Model A simple picture of a real process, used to make predictions.
Observe To watch carefully and note what happens.
Population The whole group that a sample is taken from.
Prediction A statement of what you expect to happen.
Record To write down each result as it happens.
Relative This kind of frequency is the count of a result divided by the number of trials.
Repeat To do again. More of these bring results closer to the true value.
Sample A part of a group, chosen to tell you about the whole group.
Simulation An imitation of a real process, run to see what might happen.
Survey A set of questions asked of a sample of people.
Theoretical The probability you work out by counting outcomes, not by testing.
Uniform The kind of distribution in which every outcome is equally likely.
Variable A random one is a quantity whose value depends on chance.

From the chance scale to sample spaces

Under Start from a list, The Probability Scale runs from Impossible through Unlikely and Even chance to Certain. Words of Chance has Possible, Random, Fair and Biased. Coins, Dice and Spinners holds what a class tests with: Marble, Deck, Shuffle, Replacement. Outcomes and Events has Sample space, Favorable, Complement and Independent.

Counting and experiments

Counting the Outcomes has Tree diagram, Combination, Permutation and Factorial. Experiments and Predictions sets Theoretical beside Empirical, with Frequency, Simulation and Expected.

Sample space, Tree diagram, Venn diagram, Number line, Even chance and Equally likely hide closed up: SAMPLESPACE.
Easy Probability has 43 words of three to five letters for younger classes: Coin, Dice, Flip, Odds, Fair.
Tick Show clues, not words and Outcome prints as "One possible result of an experiment."

Questions and answers

What are the words used in probability?

The everyday ones place an event on a scale: impossible, unlikely, even chance, likely, certain. The working ones name the parts of an experiment: trial, outcome, event, sample space. All of them are on this page, each with a one-line meaning.

What is the difference between an outcome and an event?

An outcome is one possible result of an experiment, such as rolling a 3. An event is a set of outcomes, such as rolling an odd number, which takes in 1, 3 and 5.

What does a probability of 0 or 1 mean?

A probability is a number from 0 to 1. Zero means the event is impossible and 1 means it is certain. A fair coin lands heads with probability one half, also written 0.5 or 50%.

What is a sample space?

The set of all possible outcomes of an experiment. For one roll of a die it is 1, 2, 3, 4, 5 and 6; for one toss of a coin it is heads and tails.

Is it die or dice?

Die is the singular and dice the plural, though dice is sometimes used for one as well. Both words are in the Coins, Dice and Spinners list.
