Three events A, B and C have probalities...

Three events A, B and C have probalities `2/5,1/3 and 1/2`, respectively. If, `P(AcapC)=1/5and P(BcapC)=1/4`, then find the values of P(C/B) and `P(A'capC')`

Text Solution

Verified by Experts

Here, `P(A)=2/5,P(B)=1/3,P(C )=1/2,P(AcapC)=1/5and P(BcapC)=1/4`
`therefore P(C //B)=(P(BcapC))/(P(B))=(1//4)/(1//3)=3/4`
and `P(A'capC')=1-P(AcupC)=1-[P(A)+P( C)-P(AcapC)]`
`=1-[2/5+1/2-1/5]=1-[(4+5-2)/10]=1-7/10=3/10`
