The letters of the word PRABABILITY are ...

The letters of the word PRABABILITY are written down at random in a row. Let `E_1` denotes the event that two Is are together and `E_2` denotes the event that `B ' s` are together, then `P(E_1)=P(E_2=3/(11)` (b) `P(E_1nnE_2)=2/(55)` `P(E_1uuE_2)=(18)/(55)` (d) `P((E_1)/(E_2))=1/5`
