If `A` and `B` are two events such that `P(A)=0.3`, `P(B)=0.25`, `P(AnnB)=0.2`, then `P(((A^(C ))/(B^(C )))^(C ))` is equal toA. `(2)/(15)`B. `(11)/(15)`C. `(13)/(15)`D. `(14)/(15)` |

Answer» Correct Answer - A `(a)` `P(((A^(C ))/(B^(C )))^(C ))=1-P((A^(C ))/(B^(C )))` `=1-(P(A^(C )nnB^(C )))/(P(B^(C )))` `=1-(1-P(AuuB))/(1-P(B))` `=1-(1-P(A)-P(B)+P(AnnB))/(1-P(B))` `=1-(0.65)/(0.75)=1-(13)/(15)=(2)/(15)` |
