.Therefore, the probability of drawing a second red marble = 1/14.Then, the probability of drawing two red marbles = (2/15) x (1/14) = 1/105.Hence, the probability that these two marbles drawn will both be red is 1/105.
The given data are as follows:
There are 2 red marbles. There are 3 green marbles. There are 10 white marbles. There are no other marbles. A probability is the number of desired outcomes divided by the total number of possible outcomes. It ranges from 0 to 1. A probability of 0 denotes that the event will never occur, while a probability of 1 indicates that the event will definitely occur. Therefore, the total number of marbles = 2 + 3 + 10 = 15.Let’s assume that the first marble that is drawn is red. The probability of this happening is 2/15.Let's suppose that the second marble is drawn, then the number of red marbles has decreased by 1, and the total number of marbles has decreased by 1
