Answer

Explanation:

Step1: Calculate total number of cards

$7 + 6+3 + 4=20$

Step2: Calculate probability of picking baseball card

The number of baseball cards is 7. Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$, so the probability of picking a baseball card is $\frac{7}{20}$.

Answer:

$\frac{7}{20}$
