Question

One card is drawn from a well-shuffled deck of 52 cards. Calculate the probability that the card will not be an ace.

• A. $\frac{12}{13}$
• B. $\frac{11}{13}$
• C. $\frac{10}{13}$
• D. $\frac{9}{13}$

Answer 1

Answer: (A)

$\frac{12}{13}$

Total number of cases$=52$
Favorable number of cases$=48$ (other than ace cards)
Therefore, probability=favorable cases/total cases=$\frac{48}{52}=\frac{12}{13}$
