The experimental probability of a simple event is P(event) = number of times an event occurstotal number of trials

Question

EXAMPLE: The following line plot shows the students’ birthdays in a class. Compare the theoretical and experimental probability.

Based on the data from the class, experimental P(Tuesday) = 525=15=0.2=20%

Because there are 7 days in a week, theoretical P(Tuesday) = 17=0.14=14%
Please complete the following question:

In experiment, a coin is flipped 30 times and the results are

{H, H, H, T, T, T, T, H, T, H, H, T, H, H, H, T, T, H, H, H, T, H, T, T, H, T, H, H, H, H}.

Heads: 18

Tails: 12

Answer 1

Determine the experimental P(head) = 18/30 = 0.6

Determine the theoretical P(head) = 0.5

The theoretical probability is equal to the experimental probability the coin landing on heads.
