Abicycle manufacturer is studying the reliability of one of its models. the study finds that the probability of a brake defect is 4 percent and the probability of both a brake defect and a chain defect is 1 percent.
if the probability of a defect with the brakes or the chain is 6 percent, what is the probability of a chain defect?

The probability of a chain defect is 3%.

Step-by-step explanation:

Given : A bicycle manufacturer is studying the reliability of one of its models. The study finds that the probability of a brake defect is 4 percent and the probability of both a brake defect and a chain defect is 1 percent.

If the probability of a defect with the brakes or the chain is 6 percent

To find : What is the probability of a chain defect?

Solution :

Let A be the event of brake defect

and B be the event of chain defect.

We have given, P(A)= 4%=0.04

P(A and B) = 1%=0.01

P(A or B)= 6%=0.06

We have to find P(B),

The formula used is,

Substitute the value,

or

Therefore, The probability of a chain defect is 3%.
