Text Solution

`P(A)=P(B)=(3)/(11)``P(AnnB)=(2)/(165)``P(AuuB)=(7)/(31)``P(B//A)=(1)/(15)`

Answer :

B::DSolution :

`(b,d)`In the word ''POSSIBILITY'' there are `2S's`, `3I's` and `6` other different words. <br> `P(A)=((10!)/(3!))/((11!)/(3!2!))=(2)/(11)` <br> `P(B)=((9!)/(2!))/((11!)/(3!2!))=(3)/(55)` <br> `P(AnnB)=(8!)/((11!)/(3!2!))=(2)/(165)` <br> `P(AuuB)=P(A)+P(B)-P(AnnB)` <br> `=(2)/(11)+(3)/(55)-(2)/(165)=(30+9-2)/(165)=(37)/(165)` <br> `P(B//A)=(P(AnnB))/(P(A))=((2)/(165))/((2)/(11))=(1)/(15)`**Introduction and definition**
