Assume that when adults with smartphones are randomly selected, 48% use them in meetings or classes. If 8 adult smartphone use

Lisa [10]

Answer:

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

$P(x) = \frac{n!}{x!(n-x)!} *p ^ n *q ^{n-x}\\\\ P(x = 5) = \frac{8!}{5!(8-5)!} * 0.48 ^ 8 * 0.52 ^ 3\\\\ P(x = 5) = 0.02218$

The probability is 2.2%

A number, n, is multiplied by - 5/8. The products is - 0.40 What is the value of n? It would also help if you would explain how

Kay [80]

I'm not sure if those numbers are negatives or thats just a hyphen but:

N(-5/8)=-0.40

Division is always the opposite of multiplication

-0.40/(-5/8)=0.64

N=0.64
