Question

you pick a card at random. what is p(7)? write your answer as a fraction or whole number.

Explanation:

Step1: Determine total outcomes

There are 3 cards, so total outcomes = 3.

Step2: Determine favorable outcomes

There is 1 card with number 7, so favorable outcomes = 1.

Step3: Calculate probability

Probability formula is $P(A)=\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}$, so $P(7)=\frac{1}{3}$.

Answer:

$\frac{1}{3}$
