I'll go out on a limb and suppose you're given the matrix
and you're asked to find the determinant of
, where
and given that
.
There are two properties of the determinant that come into play here:
(1) Whenever a single row/column is scaled by a constant
, then the determinant of the matrix is scaled by that same constant;
(2) Adding/subtracting rows does not change the value of the determinant.
Taken together, we have that

Answer:
Total number of people = 13
A:
Number of ways to choose 10 players to take the field = 13C10
=
= 286
B:
This is given as: 13P10
= =
= 1037836800
C:
This is given as:
(3C1 x 10C9) + (3C2 x 10C8) + (3C3 x 10C7)
Solving this we get the answer as = 285
