Answer :

The correct probability from the two-way table is given as follows:

B. P(120 lb | 2,000 - 2,500 cal) is different of P(120 lb).

How to calculate a probability?

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

Then the probabilities are given as follows:

  • P(1,000 - 1,500 cal | weight of 165 lb) = 15/117.
  • P(1,000 - 1,500 cal) = 140/500 -> item a is false.
  • P(120 lb | 2,000 - 2,500 cal) = 10/110 = 1/11.
  • P(120 lb) = 180/500.

Hence statement B is true.
