Explanation / Answer

Solution:-

2) The probability that he or she owns a credit card given that the student is freshman is 0.667.

Total number of freshman = 60

Number of credit card holder who are freshman = 40

The probability that he or she owns a credit card given that the student is freshman = 40/60 = 0.667

3) The probability that he or she owns a credit card given that the student is a sophmore is 0.125.

Total number of sophmore = 40

Number of credit card holder who are sophmore = 5

The probability that he or she owns a credit card given that the student is sophmore = 5/40 = 0.125.
