If A and B are two independent events, the probability that both A and B occur is 1/8 are the probability that neither of them occours is 3/8. Find th
We have, `P(AnnB)=1/8and P(barAnnbarB)=3/8` `thereforeP(A)P(B)=1/8and P(barA)P(barB)=3/8` `" "[therefore"A and B are independent"]` Now, `P(barAnnbarB)=3/8` `implies1-P(AnnB)=3/8` `or 1-(P(A)+P(B)-P(AnnB))=3/8` `or1-(P(A)+P(B))+1/8=3/8` `orP(A)+P(B)=3/4` The equation whose roots are P(A) and P(B) is `x^(2)-x{P(A)+P(B)}+P(A)P(B)=0` `or...

The probability of event `A` is `3//4`. The probability of event `B`, given that event `A` occurs is `1//4`. The probability of event `A`, given that
Correct Answer - C `(c )` `P(A)=(3)/(4)`, `P(B//A)=(1)/(4)` `P(A//B)=(2)/(3)` `P(B//A)=(P(BnnA))/(P(A))=(1)/(4)` (given) `:.P(BnnA)=(3)/(4)*(1)/(4)=(3)/(16)` Now `P(A//B)=(P(AnnB))/(P(B))=(2)/(3)`(given) `:.P(B)=(3)/(2)*(3)/(16)=(9)/(32)` `:. P(AuuB)=(3)/(4)+(9)/(32)-(3)/(16)=(24+9-6)/(32)=(27)/(32)` `:. P(A^(C )nnB^(C ))=1-P(AuuB)=1-(27)/(32)=(5)/(32)`
