The probability is the ratio of the favorable event to the total number of events. The probability of the red ball is 28/39.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

A bag contains 8 red marbles, 2 blue marbles, and 3 green marbles. If two marbles are drawn out of the bag.

Then the exact probability that both marbles drawn will be red will be

The total number of the ball will be

Total ball = 8 + 2 + 3 = 13

Then we have

[tex]\rm P = \dfrac{^{8}C_1\times ^7C_1}{^{13}C_2} = \dfrac{28}{39}[/tex]
