Question

if one card is drawn from a standard deck of 52 playing cards, what is the probability of drawing a heart?

Explanation:

Step1: Identify total and favorable outcomes

Total number of cards is $n(S)=52$. Number of heart - cards is $n(A) = 13$.

Step2: Apply probability formula

The probability formula is $P(A)=\frac{n(A)}{n(S)}$. Substituting values, we get $P(A)=\frac{13}{52}=\frac{1}{4}$.

Answer:

$\frac{1}{4}$
