A. C(13, 10) = 13! = 13·12·11 = 13 · 2 · 11 = 286.C(13, 10) = 13! = 13·12·11 = 13 · 2 · 11 = 286.
B. P(13,10)= 13! =13! =13·12·11·10·9·8·7·6·5·4.
(13−10)! 3!
C. f there is exactly one woman chosen, this is possible in C(10, 9)C(3, 1) =
10! 3!
9!1! 1!2!
10! 3!
8!2! 2!1!
10! 3!
7!3! 3!0!
= 10 · 3 = 30 ways; two women chosen — in C(10,8)C(3,2) =
= 45·3 = 135 ways; three women chosen — in C(10, 7)C(3, 3) =
= 10·9·8 ·1 = 120 ways. Altogether there are 30+135+120 = 285

The simplest form of the given expression can be written as -5x² + 25x - 3.
The given parameters:
2x(x + 6) - 7x² + (13x - 3)
The given expression can be simplified as follows;
2x(x + 6) - 7x² + (13x - 3)
= 2x² + 12x - 7x² + 13x - 3
<em>collect similar terms together</em>
= (2x² - 7x²) + (12x + 13x) - 3
= -5x² + 25x - 3
Thus, the simplest form of the given expression can be written as -5x² + 25x - 3.
