Question

A firm has two computer systems available for processing telephone orders. At any given time, system A has a 10% chance of being “down”, while system B has just a 5% chance of being “down”. The computer systems operate independently. For a typical telephone order, determine the following:

What is the probability that exactly one of the computer systems will be operational

Step 1

We are given that a firm has two computer systems available for processing telephone orders. At any given time, syste...
