Question

a jar of an unknown amount of red, blue, and yellow marbles sits before you. marbles are put back into the jar before the next random pull. what is the probability of pulling a blue marble?

Explanation:

Step1: Count the total number of marbles

Count all marbles in the jar. Assume there are \(n\) marbles.

Step2: Count the number of blue marbles

Count the number of blue marbles. Assume there are \(m\) blue marbles.

Step3: Calculate the probability

The probability \(P\) of pulling a blue marble is \(P=\frac{m}{n}\times100\%\). From the jar image, if we count: total marbles \(n = 27\) (approximate count from visual - assume this based on typical problem setups in such interfaces), blue marbles \(m = 10\) (approximate visual count). Then \(P=\frac{10}{27}\times100\%\approx 37\%\)

Answer:

\(37\%\)
