Of those, 58% indicated they take a multi-vitamin. Calculate the probability that a randomly chosen US adult does not take a multi-vitamin. Round your answer to the nearest hundredths (0.00)

Explanation / Answer

8)

P(person takes multivitamin)

= Number of people taking multivitamin/ total

Number of people taking multivitamin = 13787*6/10*0.58

Thus, P(person takes multivitamin) = (13787*6/10*0.58)/ 13787

= 0.35

9)

P(person does not take multivitamin) = 1 - P(person takes multivitamin)

= 1 – 0.35 = 0.65
