Alocal country club has a membership of 600 and operates facilities that include an 18-hole championship golf course and 12 tennis courts. before deciding whether to accept new members, the club president would like to know how many members regularly use each facility. a survey of the membership indicates that 65% regularly use the golf course, 49% regularly use the tennis courts, and 7% use neither of these facilities regularly. what is the probability that a worker regularly uses both golf and tennis facilities?

a. 49
b. 21
c. 70
d. 93

Probability that a worker regularly uses both golf and tennis facilities would be 0.21 or 21%.

Step-by-step explanation:

Since we have given that

Probability that it regularly use the golf course = 65% = 0.65

Probability that it regularly use the tennis courts = 49% = 0.49

Probability it use neither of these facilities regularly = 7% = 0.07

So, Probability that it use either of these facilities regularly would be

So, using "Probability rules", we get that

Hence, probability that a worker regularly uses both golf and tennis facilities would be 0.21 or 21%.
