Question

I need help with problem B how to set it up. Probably of selecting someone who is 45 or over

Answer 1

You can add the probabilities for 45-64 years, 64-74 years, and 75 years or over to find the total probability.

So 24.8+9.6+6.6 = 41%

Hope that helps

Answer 2

41% out of 100 you add up the percentage of all the ages 45 and older
