A sample of 100 wood and 100 graphite tennis rackets are taken from the warehouse. If 15 wood and 20 graphite are defective and one racket is randomly selected from the sample, find the probability that the racket is wood or defective.
Answers
Probability Wood is 100/200 and the Probability defective would be 35/200
Probability for both would just be 15/200
(100+35-15)/200=(120/200)
