Question

Assume that when adults with smartphones are randomly selected, 57% use them in meetings or classes. If 13 adult smartphone users are randomly selected, find the probability that fewer than 4 of them use their smartphones in meetings or classes. The probability is nothing. (Type an integer or decimal rounded to four decimal places as needed.) I am needing help with this problem.

1)
Assume that when adults with smartphones are randomly selected, 53%
use them in meetings or classes. If 10 adult smartphone users are
randomly selected, find the probability that at least 5 of them use
their smartphones in meetings or classes.(Round to 4 decimal places
as needed)
