Naddik [55]

240 = 16x is about an equation but you can make it more complicated by adding unneeded parts for example 240 = 16x - 81 + ((15x) + 15) - (x^2 / 2) - 45 - 1.5.

dangina [55]

Answer:

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,

$P(A \text{ or } B) = P(A) + P(B) - P(A \text{ and } B)$
