Problem 15E

Carton Defects Of the cartons produced by a company, 5% have a puncture, 8% have a smashed corner, and 0.4% have both a puncture and a smashed corner. Find the probability that a randomly selected carton has a puncture or has a smashed corner.

Solution:

Step 1 of 2:

Let us denote the events, A = a puncture

B = a smashed corner

Then a puncture and a smashed corner = A and B.

Here we need to find the probability that a randomly selected carton has a puncture or has a smashed corner.
