The experimental probability of a simple event is P(event) = number of times an event occurs total number of trials
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) = 5/25=1/5=0.2=20%
Because there are 7 days in a week, theoretical P(Tuesday) =1/7=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
Round your answer to the tenth place (one digit).
Determine the experimental P(head) =
Determine the theoretical P(head) =
Question 2
The theoretical probability is (<, >, =) the experimental probability the coin landing on heads.
Experimental P(head) = 18/30 = 0.6
Theoretical P(head) = 1/2 = 0.5
Question 2
The theoretical probability is = the experimental probability the coin landing on heads.
