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

Explanation:

Step1: Count red balls

There are 5 red balls.

Step2: Count total balls

There are 13 balls in total (5 red + 4 blue + 4 green).

Step3: Calculate probability

The probability of choosing a red ball is the number of red balls divided by the total number of balls. The formula for probability $P(A)=\frac{n(A)}{n(S)}$, where $n(A)$ is the number of favorable outcomes (red balls) and $n(S)$ is the total number of outcomes (all balls). So the probability is $\frac{5}{13}$, and the numerator is 5.

Answer:

5
