1.	Les A, B and C be three mutuallyand exhaustive events.find P (B), if 1/3 P (c)= 12 P (A) = P(B)
Answer» <P>Answer: 12/49 Step-by-step EXPLANATION: P(c)=36P(a)=3P(b) MUTUALLY exhaustive => ΣP(i)=1 =>P(a)+P(b)+P(c)=1 =>1/12P(b)+p(b)+3P(b)=1 49/12 P(b) =1 therefore P(b)=12/49

<P>Answer:

12/49

Step-by-step EXPLANATION:

P(c)=36P(a)=3P(b)

MUTUALLY exhaustive => ΣP(i)=1

=>P(a)+P(b)+P(c)=1

=>1/12P(b)+p(b)+3P(b)=1

49/12 P(b) =1

therefore P(b)=12/49
