# A card is selected from a pack of 52 cards.Calculate the probability the card is an ace of spades.

$\begin{array}{1 1}(A)\;\large\frac{1}{52}\\(B)\;\large\frac{3}{52}\\(C)\;\large\frac{5}{52}\\(D)\;\text{None of these}\end{array}$

Toolbox:
• The formula used to solve this problem
• Probability $P=\large\frac{n(E)}{n(S)}$
Card is an ace of spades
Let E be the event that "an ace of spade"
$\therefore n(E)=1$
Step 2:
$\therefore$ Probability of event getting an ace of spade =$\large\frac{n(E)}{n(S)}$
$\Rightarrow \large\frac{1}{52}$
Hence (A) is the correct answer.
