Question

if you close your eyes and choose a ball, what is the probability that it will be blue? simplify first! enter the numerator.

Explanation:

Step1: Count total balls

Count all the balls in the picture. There are 12 balls in total.

Step2: Count blue balls

Count the number of blue balls. There are 4 blue balls.

Step3: Calculate probability fraction

The probability of choosing a blue - ball is the number of blue balls divided by the total number of balls. So the fraction is $\frac{4}{12}$.

Step4: Simplify the fraction

Simplify $\frac{4}{12}$ by dividing both the numerator and the denominator by their greatest common divisor, which is 4. $\frac{4\div4}{12\div4}=\frac{1}{3}$. The numerator of the simplified fraction is 1.
