Question

in a class experiment, Sean finds that the probability that a student plays soccer is 12/25. if the school population is 300, how many students would we expect to play soccer, based on Sean's experiment?

Answer 1

Okay, here we have this:

Considering the provided information, we are going to calculate the requested value, so we obtain the following:

Then we will substitute in the following formula:

Students who play soccer=Number of students*(Probability that they play soccer)

Replacing:

Students who play soccer=300*(12/25)

Students who play soccer=3600/25

Students who play soccer=144

Finally we obtain that 144 students would we expect to play soccer, based on Sean's experiment.
