Question

A glass jar contains 6 red, 5 green, 8 blue and 3 yellow marbles. If a single marble is

chosen at random from the jar, what is the probability of choosing a red marble?

Answer 1

Probability [choosing a red marble] = 3 / 11

Explanation:

Given:

Number of red marble in jar = 6

Number of green marble in jar = 5

Number of blue marble in jar = 8

Number of yellow marble in jar = 3

Find:

Probability [choosing a red marble]

Computation:

Total number of marble = 6 + 5 + 8 + 3

Total number of marble = 22 marble

Probability of an outcome = Favorable outcome / Number of total outcomes

Probability [choosing a red marble] = Number of red marble in jar / Total number of marble

Probability [choosing a red marble] = 6 / 22

Probability [choosing a red marble] = 3 / 11
