Un naipe inglés consta de 52 cartas repartidas en cuatro pintas distintas, de las cuales dos son rojas (corazón y diamante) y dos son negras (pique y trébol). Cada pinta consta de 3 figuras: rey (K), dama (Q), caballero (J) y de 10 cartas numeradas desde 1 (as) a 10, entonces, la probabilidad de obtener un "AS" de las 52 cartas de una baraja inglesa es:

P = 4/52 = 0.077 or 7.7%

Step-by-step explanation:

I will answer in English.

We have a deck of 52 cards, and we want to find the probability of drawing, at random, a 1.

We have 4 1's in the deck, one for spades, one for hearts, one for diamonds and one for clovers.

So the probability can be calculated as the quotient between the total number of 1's in the deck and the total number of cards in the deck, this is:

P = 4/52 = 0.077
