Answer:

a. The expected number of adults who smoke is 70

b. The probability that fewer than 20 smoke is 5.7%

c. The probability that from 45 to 80 smoke is the 12,8% to 22,8%

d. The probability that 70 or more smoke is the 20%

Explanation:

a. 350 is the 100% so you have to do a equation

350 -100%

X - 20% = 20% x 350/100 = 70 adults

b. 350 -100%

20 - X = 20% x 100%/350= 5.7% probability

c. 350 - 100%

45 - X = 45 x 100%/350= 12.8% probability

350 - 100%

80 - X = 80 x 100%/350= 22.8% probability

d. 350 - 100%

70 - X = 70 x 100%/350= 20% probability
