Question

A building company bids on two large projects. The CEO believes the chance of winning the 1st is 0.6, the chance of winning the 2nd is 0.5, and the chance of winning both is 0.3. What is the chance of winning at least one of the jobs?

Answer 1

Answer:

0.8

Step-by-step explanation:

A: P(1) = .6, P(2) = .5, P(1 and 2) = .3

P(1 or 2) = P(1) + P(2) - P(1 and 2) .6 + .5 - .3 = 0.8
