a. randomly selecting a mother 30-39 years old
b. randomly selecting a mother not 30-39 years old
c. randomly selecting a mother less than 45 years old
d. randomly selecting a mother at least 20 years old

Please read the answers below.

Step-by-step explanation:

A. Randomly selecting a mother 30-39 years old

Mother 30 - 39 years old = Mother 30 - 34 % + Mother 35-39%

Mother 30 - 39 years old = 37.3 + 24.5

Mother 30 - 39 years old = 61.8%

B. Randomly selecting a mother not 30-39 years old

Mother not 30-39 years old = 100% - Mother 30-39 years old%

Mother not 30-39 years old = 100 - 61.8

Mother not 30-39 years old = 38.2%

C. Randomly selecting a mother less than 45 years old

Mother less than 45 years old = 100% - Mother 45 -54 %

Mother less than 45 years old = 100 - 3.8

Mother less than 45 years old = 96.2%

D. Randomly selecting a mother at least 20 years old

Mother at least 20 years old = 100% - Mother 15 -19%

Mother at least 20 years old = 100% - 1.3%

Mother at least 20 years old = 98.7%
