Answer:
<u>Please read the answers below.</u>
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
<u>Mother 30 - 39 years old = 61.8%</u>
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
<u>Mother not 30-39 years old = 38.2%</u>
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
<u>Mother less than 45 years old = 96.2%</u>
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%
<u>Mother at least 20 years old = 98.7%</u>
