If he must answer the last question, he effectively needs to select 6 from 10. This can be done in 10C6 = 10*9*8*7/(4*3*2*1) = 210 ways.
If he must include the last question, then his choices really boil down tohow many ways he can select 4 more from the remaining 11.The number of ways he can select 4 from 11 is (11 x 10 x 9 x 8) = 7,920 ways .But each group of 4 can be selected in 24 different ways.So he can only wind up with 7920/24 = 330 different groups of questions.
10 people can line up in (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2) = 3,628,800 different ways.
Assuming the Ps and Is are indistinguishable: There are 10! / 3! / 3! = 100800 ways If the Ps and Is are distinguishable, then there are 10! = 3628800 ways

I'm going with 25,200 3 men out of 10 may be chosen in 10C3 ways = 10 ! / 3! 7 ! = 120 ways. 4 women may be chosen out of 10 in 10C4 = 10 ! / 4! 6! ways = 210 ways. Therefore, a committee with 3 men and 4 women can be formed in 120 x 210 = 25,200 ways.

There are 1 001 ways a person may select 10 shirts from a collection of 14. To calculate this result you use the expression: 14C10 = 14!/[10!∙(14-10)!] where the symbol !, stands for factorial, such that: n! = n∙(n-1)∙(n-2)∙(n-3)∙,,,∙(4)∙(3)∙(2)∙(1) e.g., 5! = 5x4x3x2x1 = 120 The expression 14C10 will give the number of different 10 entity combinations you can make from a collection of 14 different entities.
