Assume that when adults with smartphones are randomly selected, 48% use them in meetings or classes. if 8 adult smartphone users are randomly selected, find the probability that exactly 5 of them use their smartphones in meetings or classes. the probability is

The probability is 2.2%

Step-by-step explanation:

The probability that a randomly selected adult uses the telephone in classes is always equal to 0.48.

If x represents the number of adults selected from among the 8 that the telephone uses in classes, then x is a discrete random variable that follows a binomial distribution, with:

p = 0.48

q = 0.52

n = 8

We want to find the probability of x = 5

The probability is 2.2%

over the argument its not good to fight.
