CHANCE AND PROBABILITY

Statistics of Class 8

CHANCE AND PROBABILITY:

EXPERIMENT:

An activity which gives some well-defined outcomes is called experiment “Tossing a coin” gives either head (H) or tail (T), is an experiment.

RANDOM EXPERIMENT:

It is an experiment, in which we know about all the possible out comes but not sure about a specific outcome.

For e.g. in throwing a dice, possible outcomes are 1, 2, 3, 4, 5, 6 but we are not sure that the number on dice is ‘4’.

EVENT:

The possible outcomes of a trial are called events. e.g., when a die is rolled, showing the number 1 or 2 or 3 or 4 or 5 or 6 is an event.

EQUALLY LIKELY EVENTS:

Outcomes of an experiment are equally likely if each has the same chance of occurring.

Probability of an event = when the outcomes are equally likely.

P (E) + P (not E) =  1

0 ≤ P (E) ≤ 1

Sum of the probabilities of all the outcomes of random experiment is 1.
