Answer:

14/15

Step-by-step explanation:

1. Convert the fractions to have the same denominator

Remember that you can only add fractions with the same denominator

To find the common denominator, find the LCM of 5 and 3 which is 15.

-2/5 * 3/3 = -6/15 and 4/3 * 5/5 = 20/15

Westkost [7]

Answer:

10.2% of adults will belong to health clubs and will go to the club at least twice a week

Step-by-step explanation:

assuming that the event H=an adult belongs to a health  club  and the event T= he/she goes at least twice a week , then if both are independent of each other:

P(T∩H)= P(H)*P(T)  ( probability of the union of independent events → multiplication rule )

replacing values

P(T∩H)= P(H)*P(T) = 0.20 * 0.51 =0.102

then  10.2% of adults will belong to health clubs and will go to the club at least twice a week
