Answer

Explanation:

Step1: Count total marbles

There are 7 marbles in total.

Step2: Count favorable marbles

There are 2 blue and 1 yellow marble, so 2 + 1=3 favorable marbles.

Step3: Calculate probability

The probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P = \frac{3}{7}$.

Answer:

$\frac{3}{7}$
