Thirty percent of consumers prefer to purchase electronics online. You randomly select 8consumers. Find the probability that the number of consumers who prefer to purchase electronics online is (a) exactly five, (b) more than five, and (c) at most five.

Step 1

Given:

Probability of success (*p*) = 0.30

Number of trials (*n*) = 8

Consider, *X* be the random variable that represents the number of consumers who prefer to purchase electronics online is binomially distributed with the parameters *n= *8 and *p* = 0.30, that is,

Step 2

(a)

The probability that the number of consumers who prefer to purchase electronics online is exactly 5 can be computed as:

Step 3

(b)

The probability that the number of consumers who prefer to purch...
