Problem 75E

Calculate the mean for the random variable in Exercise 3-37.

Step-by-Step Solution:

Solution:

Step 1 of 2:

A circuit consist of two devices which connected parallely.

The device failed independently.

The probability that each device functions is 0.8 and 0.9 respectively.

So the probability that each device failed is 0.2 and 0.1 respectively.

We have to find the mean of the random variable X.
