Answer 1

Answer:

A,B and C are three students appear in an examination.

p(A)=2P(B)=3p(C)

A,B and C are mutually exclusive and exhaustive event.

p(AUBUC)=1

p(A)+p(B)+p(C)=1

p(A)+1/2p(A)+1/3p(C)=1

p(A)[1+1/2+1/3]=1

p(A)[11/6]=1

p(A)=6/11

p(B)=3/11

p(c)=2/11

so,The probability of A's success is p(A)=6/11
