Question

Assume that when adults with smartphones are randomly selected, 36% use them in meetings or classes. If 66 adult smartphone users are randomly selected, find the probability that exactly 44 of them use their smartphones in meetings or classes.

The probability is ????. (Round to four decimal places as needed.)

Answer #1

Given the probability that adult smartphone users use their smartphones in meetings or classes is p=0.36

Let X be the number of adult smartphone users use their smartphones in meetings or classes.

Therefore,

The probability that exactly 44 of them use their smartphones in meetings or classes given by:
