Explanation / Answer

7) n(S) = 10 and n(A) = 4
P(A) = n(A) / n(S) = 4/10 = 0.40

8)a) P(A and C ) = n(A and C) / n(S)
= 2/ 10 = 0.20

b) No
since P(A and C) is not equal to zero

9)

a) P(B/A) = P(A and B) / P(A)
= (1/10) / (4/10) = 1/4 = 0.25

b) P(B) = n(B) / n(S) = 4/10 = 0.4

Here P(B/A) not = P(B)
Therefore A and B are not independent

10) P(A or B) = P(A) + P(B) - P(A and B)
= 0.4 + 0.4 - 0.1 = 0.7

11) P(A/C) = P(A and C) / P(C) = 2/10 / 5/10 = 2/5 = 0.4
