Question

A jar contains 3 red, 4 blue, and 2 white marbles. What is the probability that a marble drawn at random is not red?

Answer 1

Answer:

Probability that a marble drawn at random is not red = $\frac{2}{3}$.

Step-by-step explanation:

Given : A jar contains 3 red, 4 blue, and 2 white marbles.

To find  : What is the probability that a marble drawn at random is not red.

Solution : We have given that

Red marbles = 3.

White marbles = 2.

Blue marbles = 4

Total marbles = 9

Marbles that are not red = white + blue =2+4 = 6.

Probability that a marble drawn at random is not red = $\frac{Number\ of\ marbles\ not\ red}{Total\ that\ number\ of\ marbles}$.

Probability that a marble drawn at random is not red = $\frac{6}{9}$.

Probability that a marble drawn at random is not red = $\frac{2}{3}$.

Therefore, Probability that a marble drawn at random is not red = $\frac{2}{3}$.

Answer 2

2/3 is the probability that a marble drawn at random is not red.
