Answer 2

Answer 3

They will have a 4 in 52 chance to draw an ace on the first card, followed by a 3 in 51 chance on the second:
\[\frac{4}{52}\frac{3}{51}=\frac{12}{2652}=0.004524\]

your choose notation gives the same results

Answer 4

So...My answer is correct @Mathmuse

Answer 5

but 4C2 = 4!/2! * 2! = 3

52C2 = 52! / 50! 2! = 26 * 51

3/ 26 * 51 = 3/26 * 17 = 1/442

Answer 7

\[4C2=\frac{4!}{2!(4-2)!}=\frac{24}{2(2)}=6\]
