Answer to Problem 78E

Probability for the randomly selected adult belongs to a health club and goes there at least twice a week is 0.04.

Explanation of Solution

Given information:

10% of the adults belong to health clubs.

40% of these health club members go to the club at least twice a week.

Calculations:

According to general multiplication rule,

  P(AandB)=P(AB)=P(A)×P(B|A)=P(B)×P(A|B)

Let

H: adults belong to health clubs

W: health club members go to the club at least twice a week

Now,

The corresponding probabilities:

Probability for the adults belong to health clubs,

  P(H)=0.10

Probability for the health club members go to the club at least twice a week,

  P(W|H)=0.40

Apply the general multiplication rule:

  P(HandW)=P(HW)=P(H)×P(W|H)=0.10×0.40=0.04

Thus,

Probability for a randomly selected adult belongs to a health club and visit club at least twice a week is 0.04.
