It is hard to show work for this problem because it very similar to a basic addition or subtraction problem.
Just so you have the answer and how to solve. -27 is the answer. Think about it like 41-14 then add the negative back. But I would strongly suggest not writing that as work because you teacher might get confused about what you are doing

3. According to the U.S. census website (www.census.gov), based on the U.S. population in 2010, the probability that a randomly

Oksi-84 [34.3K]

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
