Hint: Here we are given in total 2P, 3A, B, O, L
Now to form a 3 letter word, take the different cases as (1) all differnt (2) 2 same and 1 different, in this case we again we have two possibilty that these 2 same either can be from P or A accordingly find the no. of words and last case is (3) all different. Count all the no. of total possibility and get your answer.

Thanks, Vijay
