Question

if A,B and C are three mutually exclusive and exhaustive events, Find p(b), if 1/3 p(c)=1/2P(A)=P(B).​

Answer 1

Answer:

if A. B and c are three mutually

Answer 2

Step-by-step explanation:

Let p(A)=p. then,

P(B)=3/2 p(A) => P(B)=> 3/2 and p(c) = 1/2 p(B) => 3/4p

since A,B,C are mutually exclusive and exhaustive events associated with a random

A u B u C = S

p (A u B u C ) = p (S)

p ( A u B u C ) = 1

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

p + 3/2p + 3/4 = 1

p = 4/13

p(A) = 4/13
