In a lottery, a person choses six different natural numbers at random from 1 to 20, and if these six numbers match with the six numbers already fixed by the lottery committee, he wins the prize. What is the probability of winning the prize in the game? [Hint order of the numbers is not important.

 12

Check whether the following probabilities P(A) and P(B) are consistently defined

(i) P(A) = 0.5, P(B) = 0.7, P(A B) = 0.6


(ii) P(A) = 0.5, P(B) = 0.4, P(A B) = 0.8

 14

Given P(A) = and P(B) =. Find P(A or B), if A and B are mutually exclusive events.

 15

If E and F are events such that P (E) =, P(F) = and P(E and F) =, find

(i) P (E or F)


(ii) P (not E and not F).
