Question

in a ball pit 75% of the balls are yellow in color. if you randomly pick a ball from the ball pit, what is the probability that the ball picked is not one of the yellow balls? a. 1/4 b. 1/2 c. 3/4 d. 1/8 e. 7/8

Explanation:

Step1: Calculate the probability of yellow balls

The probability of yellow balls \(P(Y)=75\%=\frac{75}{100}=\frac{3}{4}\)

Step2: Use the complement rule

The probability of non - yellow balls \(P(\text{not }Y)=1 - P(Y)\)
Substitute \(P(Y)=\frac{3}{4}\) into the formula: \(P(\text{not }Y)=1-\frac{3}{4}=\frac{4 - 3}{4}=\frac{1}{4}\)

Answer:

A. \(\frac{1}{4}\)
