Question

you pick a card at random.
what is p(2 or factor of 21)?
simplify your answer and write it as a fraction or whole number.

Explanation:

Step1: Identify total possible outcomes

Total cards = 3, so total outcomes = 3

Step2: Find favorable outcomes

First, list factors of 21: 1, 3. We need cards that are 2 OR a factor of 21. Favorable cards: 1, 2, 3. Count = 3

Step3: Calculate probability

Probability = $\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}$ = $\frac{3}{3}$

Step4: Simplify the fraction

$\frac{3}{3} = 1$
