Question

what is the probability of drawing a black 10 from a deck of cards

Answer 1

A deck of cards has a total of 52 cards.

Among these cards, we have 4 cards that have the number 10, 2 are red and 2 are black.

So, if the number of black 10's in a deck is 2, the probability of drawing a black 10 is the number of black 10 over the total number of cards:

$P=\frac{2}{52}=\frac{1}{26}$
