Q.3. (a) Let an experiment consist of tossing two standard
dice. Define the events, A = {doubles appear} (That is (1, 1), (2,
2) etc..)
B = {the sum is bigger than or equal to 7 but less than or
equal to 10}
C = {the sum is 2, 7 or 8}
(i) Find P (A), P (B), P (C) and P (A ∩ B ∩ C). (ii) Are
events A, B and C independent?
(b) Let the sample space S consist of the 3! permutations of
letters a, b and c along with three triples of each letter (e.g.
aaa) and let each element of S have probability
1 Define Ai = {i-th place in thee triple is occupied by a}, i
= 1, 2, 3. 9.
Verify whether or not A1,A2 and A3 are independent?
