Explanation:

Step1: Count the number of blue marbles and total marbles

Assume there are \( b \) blue marbles and \( t \) total marbles. The probability formula is \( P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \). Here, the number of favorable outcomes (pulling a blue marble) is \( b \), and the total number of outcomes (pulling any marble) is \( t \).

Step2: Calculate the proportion

Count the blue marbles (let's say there are 9 blue marbles) and total marbles (16 total marbles). Then \( P = \frac{9}{16}=0.5625 = 56.25\%\approx57\%\) (by visual - counting in the jar image).

Answer:

57%
