A bag contains 4 mangoes and 5 oranges .In how many ways can I make a selection so as to take at least one from each.
All mangoes orange are alike .
So , I put 4 mangoes in one basket and 5 in another.
Mmmm Ooooo
From the mangoes basket I can select *any* one or two or three or four --->(1+2+3+4)
Similarly for orange (1+2+3+4+5)
Both events of selection will happen simultaneously,
10*15=150 ??
If all are Distinct then 2^9 -1
Both ways Answer is not coming
