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%.

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
