there will be three cases
when there are three bowlers .- 13C7 X 2C1 X 5C3
when there are 4 bowlers - 13C6 X 2C1 X 5C4
when there are 5 bowlers - 13C5 X 2C1 X 5C5
NOW ADD ALL OF THEM

BF3 HAVE CONFIGURATION 1s2 2s2 2p1
so we have s orbital with 2 electrons and 1 electron in p orbital in ground state in 2nd shell.in excited state s orbital will have 1 electron&p orbital will have 2 electrons.now 1 flourine needs 1 electron to complete its octet.
so now as B HAVE 3 valence electrons in s and p orbitals.so 3 F WILL TAKE THESE 3 ELECTRONS TO have its octet complete and B will have its 1 s orbital overlap with 1 F AND 2 p with 2 remaining flourine .SO B HAS SP3 HYBRIDISATION IN BF3 .
NH3 HAS SP3 HYBRIDISATION
