A random study of recent graduates' average grades and degrees showed the following results.
Grade
Degree C B A
B.S. 6 9 13
B.A. 5 12 10
If a graduate is selected at random, find these probabilities.
1.The graduate has a B.S. degree, given that he or she has an A average.
2.Given that the graduate has a B.A. degree, the graduate has a C average.
3.What is the probability that a person has a B.S. degree and a B?
4.What is the probability that a graduate has neither an A nor a C.
