Probability of starting hands

[kinghippo423]

The chances to get a pocket pair is (52/52 * 3/51). Why?

On the first card, you have a 52/52 chance to have a part of a pocket pair

On the second card, assuming to got a 7, you have 3/51 to get another 7.

P(get a pocket pair) = 52/52 * 3/51 = 5.88%

For the other question, I really don't know sorry...
