I am extremely poor in odds and probabilities. My question is "from a standard deck of 52 cards, what are the odds of getting a pair? any pair?" Thanks.
The chance of drawing any one card is 1 (it's certain because there are no other cards yet xD). The chance of getting a pair on your next card is 3/51 since there are 4 of each card and 51 left after your first pick. Multiply these together:
$\displaystyle \frac{52}{52}\cdot \frac{3}{51} = \frac{3}{51}$
