Question

A company produces digital cameras. On average 7% of the cameras has mechanical problems within 5 years. The camera also contains a battery, which needs to be replaced 12% of the time within 5 years.

What is the probability that mechanical but no battery problems occur within 5 years?

Answer 1

Answer:

Given data,

A company produces digital cameras. On average 7% of the cameras has mechanical problems within 5 years.

The camera also contains a battery, which needs to be replaced 12% of the time within 5 years.

The probability that mechanical but no battery problems occur within 5 years:

Mechanical problem in 5 years occur with probability:

=0.07

Battery problem in 5 years occur with probability:

=0.12

Since, both are independent events, and we know, for independent event.

So, the probability that mechanical but no battery problems occur within 5 years

=0.070.12

=0.0084
