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 red marble?

Explanation:

Step1: Count the number of red marbles

Assume there are \(r\) red marbles.

Step2: Count the total number of marbles

Assume there are \(t\) total marbles (red + blue + yellow).

Step3: Calculate the probability

The probability \(P\) of pulling a red marble is \(P=\frac{r}{t}\). If we assume from visual count (though exact count not clear from image but if we assume based on typical problem - like if we assume total marbles \(t = 25\) and red marbles \(r = 11\) (a common - sense visual approximation), then \(P=\frac{11}{25}=0.44 = 44\%\))

Answer:

\(44\%\)
