Complete parts (a) and (b) below.
(a) Are the events "have a Bachelor's Degree" and "never married" independent? Explain.
Suppose a woman in the country aged 25 years or older is randomly selected. What is the probability she has a Bachelor's Degree and has never married? Interpret this probability.

a) B = having Bachelor's degree
NM = never married
p(B) = 19.3% = 0.193
p(NM) = 17.2% = 0.172
p(B and NM) = 22.2% of 17.2 = 3.82% = 0.0382
Also p(B and NM) = 19.8% of 19.3 = 3.82% = 0.0382
p(B) x p(NM) = 0.193 x 0.172 = 0.0332
p(B) x p(NM) is not equal to p(B and NM)
Therefore the events "have a Bachelor's Degree" and "never married" not independent.
b) 0.0382 o
It means there are 3.82% of women in the country aged 25 years or older who have a bachelor's degree and who are never married.
