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

Answer:

$\frac{1}{3}$

Explanation:

Step1: Determine total outcomes

There are 3 cards (6, 7, 8), so total outcomes = 3.

Step2: Determine favorable outcomes

The number 7 appears 1 - time, so favorable outcomes = 1.

Step3: Calculate probability

$P(7)=\frac{\text{favorable outcomes}}{\text{total outcomes}}=\frac{1}{3}$
