Question

nswered Provide an appropriate response. According to police sources, a car with a certain protection system will be recovered 90% of the time. Find the probability that 5 of 10 stolen cars will be recovered. ut of 1 question Select one: a. 0.001 b. 0.1 c. 0.500 d. 0.9

Answer 1

Solution:

Given:

p = probability of recovered = 0.90

n = total number of cars = 10

We have to find P(X=5) = ...?

Using Binomial distribution, we can find this probability.

Formula is

n X-u P(x)= pa X

Therefore,

Pr(X = 5) = 10 5 0.905 x 0.110-5

P(X = 5) = 0.001

Option a)
