Question

Ms. Sanchez is planning two projects for her student’s final assignment. Each student will have an equal chance of selecting Project A or Project B. Ms. Sanchez flips a coin to represent each student’s choice, with heads representing Project A and tails representing Project B. After 110 trials, there are 58 heads and 52 tails. To the nearest percent, what is the experimental probability of Project B?

Answer 1

The experimental probability of an event is defined as the ratio of the number of times the event occurred to the total number of trials. In this case, the event of interest is selecting Project B, which occurred 52 times out of 110 trials.

Experimental probability of Project B = Number of times Project B occurred / Total number of trials

Experimental probability of Project B = 52 / 110

Experimental probability of Project B = 0.4727

To the nearest percent, the experimental probability of Project B is 47%.

Hope this helps, have a good day.
