Question

(80 pts) Find the probability of selecting two 10's when two cards are drawn (without replacement) from a standard deck of cards.

Answer 1

3/663 or 1/221 chance

Explanation:

A standard deck of cards contains 52 cards total, 4 suits total. Therefore there are 4 "10"s.

There is a 4/52 (simplified: 1/13) chance to draw a 10 on the first try.

To do it twice there is a 3/51 x 1/13 chance.
