Question

Let A,B,C be any three mutually exclusive and exhaustive events such that p(B)=3/2P(A) and P(C)=1/2P(B).find P(A)

Answer 1

Answer:

Step-by-step explanation:

here is ur answer hope u will satisfied

p(a) +p(b) +p(c) = 1

p(a)=p(b) is given

we can write

p(b)+ p(b)+ p(c) = 1

2p(b) + 3/2 = 1. (1/3p(c)=1/2. p(c) = 3/2)

2p(b)= 1 - 3/2

2p(b) = - 1/2

p(b) = - 1/4
