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%.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
