a. What is the appropriate model for the distribution of the proportion of students in this sample who play a musical instrument? Specify the name of the distribution, the mean, and the standard deviation.

b. What is the approximate probability that more than 40% of the sample will play a musical instrument?

would you use the geometric probability model?
