When randomly choosing two cards from a standard deck of cards without replacement, what is the probability of choosing a number card and then an ace?
A) 12/221
B) 3/169
C) 4/221
D) 9/169

Respuesta :

Number cards = 2,3,4,5,6,7,8,9,10
4 suits so 9 x 4 = 36

Ace
Because 4 suits so 4 x 1 = 4
51 because first card is taken out.

[tex] \frac{36}{52} \times \frac{4}{51} \\ = \frac{144}{2652} \\ = \frac{12}{221} [/tex]

Answer is A. 12/221
