a sample of 100 wood and 100 graphite shaft golf clubs are taken from the warehouse. if 10 wood and 25 graphite clubs are defective and one club is randomly selected from the sample, what is the probability that the club is graphite or defective?
100/200 + 35/200 - 25/200 = 110/200 = 11/20
100/200 + 35/200 - 25/200 = 110/200 = 11/20
