If a ball is drawn from a box containing 19 identical marbles; 4 of them are white, 10 are red, and the rest are green, determine the probability of the ball being yellow.
The probability of event occurring is equal to the number of
favorable outcomes divided by the total number of possible
outcomes in the sample space, In this case, event is
drawing a yellow ball. Find the probability of event as
Thus, the probability of drawing a yellow ball is 0.
