Find the number of ways of selecting 4 cards from a pack of 52 playing cards.

Question

Accepted Answer

Selecting 4 cards out of 52 without regard to order is given by the combination $^{52}C{4} = \frac{52!}{4!48!} = \frac{52 	imes 51 	imes 50 	imes 49}{4 	imes 3 	imes 2 	imes 1} = 270725$. Thus, option B is correct.
