10-2 Experimental Probability

Experimental probability is one way of estimating

the probability of an event. It is based on actual

experience or observations. Experimental

probability is found by comparing the number

of times an event occurs to the total number of

trials, the times an experiment is carried out or

an observation is made. The more trials you

have, the more accurate the estimate is likely to

be.

10-2 Experimental Probability

Writing Math

“P(event)” represents the probability that an event

will occur. For example, the probability of a flipped

coin landing heads up could be written as “P(heads).”

Recall that an outcome of an experiment can be

impossible, certain, or in between. If an event is

impossible, it will never happen in any trial.

P(impossible event) = 0

total number of trials

=0

0 divided by any number except 0 equals 0.

10-2 Experimental Probability

If an event is certain, it will always happen in

every trial. This means that the number of times

the event happens is equal to the total number of

trials.

P(certain event) = total number of trials

total number of trials

=1

Any number except 0 divided by itself equals 1.

Course 2

If an event is certain, it will always happen in

every trial. This means that the number of times

the event happens is equal to the total number of

trials.

P(certain event) = total number of trials

total number of trials

=1

Any number except 0 divided by itself equals 1.
