probabilities 9math)

Question

you select two cards of a deck of 52, what are the probabilities that both are diamonds?

Answer 1

There are 13 diamond cards in a standard deck of cards.

Assuming that the first card is not replaced after being drawn,

P(both cards are diamonds) = (13/52)(12/51) = 156/2652 = 78/1326 = 26/442 = 13/221 = 1/17
