Part (d)

Find the probability that his shirt number is from 34 to 66 OR he weighs at most 210 pounds. (Enter your answer as a fraction.)

Part (e)

Find the probability that his shirt number is from 34 to 66 GIVEN that he weighs at most 210 pounds. (Enter your answer as a fraction.)

Part (f)

If having a shirt number from 34 to 66 and weighing at most 210 pounds were independent events, then what should be true about P(Shirt # 34-66 | ≤ 210 pounds)?

It must have the same probability as weighing at most 210 pounds.
It will be the same P(Shirt #34-66 AND ≤ 210 pounds).
The probability would equal zero.
It must have the same probability as having a shirt number from 34 to 66.
