Q1) Following is based on information from Statistical abstract of the United States, Dec, 1992. In this table columns are years in which students graduated from college with Bachelor's degree. Rows are high school grade average for these students. In 1976, thus, a random sample of 577 new college students showed that 419 had a high school average of A, 123 had a grade of B and so on. (Use chart for questions 31 - 40.) Write answers in decimal form.

High School Grade Average	1976	1980	1986	Total
A	419	593	607	1619
B	123	249	280	652
C	24	61	77	162
D	11	36	45	92
Total	577	939	1009	2525

i) Calculate P(C)

ii) Calculate P(1980)

iii) Determine P(B | 1986)

iv) Determine P(1986 | A)

v) Calculate P (1976 | D)

vi) Determine P(A or B)

vii) Calculate P(C or 1976)

vii) Calculate P(A and D)

vii) Are A and B mutually exclusive?

viii) Are C and 1986 mutually exclusive?
