1.	For a post, three persons A, B and C appear in an interview. The probability of A being selected in twice that of B and the probability of B being selected is thrice that of C. If the post is filled, what are the probabilities of A, B and C being selected?
Answer» Prob of A is twice of BSo P(A) =2P (B)----1 Now Prob of B is thrice of CP (B) = 3 P(C) --2 Sub 2 in 1 P(A)=6 P(C) Total Prob is PA+PB+PC=6+3+1=10 P(A) =6/10P(B)=3/10P(C)=1/10

Answer»

Prob of A is twice of BSo P(A) =2P (B)----1

Now Prob of B is thrice of CP (B) = 3 P(C) --2

Sub 2 in 1 P(A)=6 P(C)

Total Prob is PA+PB+PC=6+3+1=10

P(A) =6/10P(B)=3/10P(C)=1/10
