Step-by-step explanation:
Answer:
a. 0.017
b. 0.013
c. 0.021
Step-by-step explanation:
Let p be the probability that a randomly selected man is 65 or older
And q be the probability that a randomly selected woman is 65 or older
Then p=0.114 and q=0.146
Using the multiplication rule for independent events:
a. If a man is selected at random and a woman is selected at random, the probability that both people selected are 65 or older is p × q = 0.114 × 0.146 ≈ 0.017
b. If two men are selected at random, the probability that both of them are 65 or older is p × p = 0.114 × 0.114 ≈ 0.013
c. If two women are selected at random, the probability that neither of them is 65 or older is q × q = 0.146 × 0.146 ≈ 0.021
