Memorize it:

Probability =
       (number of ways to be successful)
divided by
       (total number of possibilities) .

When you draw one from a deck of cards, there are 52 total possibilities.

How many red queens are there ?

Probability of drawing one from the deck = 2 / 52  =  1/26  =  about  3.8% .
