Industry standards suggest that 9 percent of new vehicles require warranty service within the first year, Jones Nissan in Sumter

aleksklad [387]

Answer:

so probability none of these vehicles requires warranty service is 0.389416

Explanation:

given data

new vehicles require warranty service π = 9 % = 0.09

sold nissan n = 10

solution

As we know here binomial probability formula that is

P(x) = $_nC_x \ \pi ^x \ (1-\pi )^{n-x}$ ......................1

so we use here combination formula that is

$_nC_r = \frac{n!}{r!(n-r)!}$ .................2

so probability none of these vehicles requires warranty service is

P(0) = $_{10}C_0 \ \pi ^0 \ (1-\pi )^{10-0}$

P(0) = $\frac{10!}{0!(10-0)!} (0.09^0) (1-0.09)^{10}$

P(0) = 0.389416

so probability none of these vehicles requires warranty service is 0.389416
