Question

What is the probability of drawing a spade from a standard deck of cards on a second draw, given that a spade was drawn on the first draw and not replaced?

Answer 1

There are 13 spades in a deck, take 1 out, leaves 12.

There are 52 cards in a deck, so I would say 12/52 = 3/13.

Check with others, I could be wrong.
