Chapter 3: Q. 117 (page 230)

A previous year, the weights of the members of the San Francisco 49ers and the Dallas Cowboys were published in the San Jose Mercury News. The factual data are compiled into Table3.24.

For the following, suppose that you randomly select one player from the 49ers or Cowboys. If having a shirt number from one to 33 and weighing at most 210 pounds were independent events, then what should be true about P(Shirt#1–33|≤210pounds)?

Short Answer

Expert verified

P(Shirt#1–33|≤210pounds)=2133

Explanation

For the following, suppose that you randomly select one player from the 49ers or Cowboys. If having a shirt number from one to 33 and weighing at most 210 pounds were independent events,

The probability that his shirt number is from 1 to 33GIVEN that he weighs at most 210 pounds.

P(1to33≤210)=2133
