Verified by Toppr

$${\textbf{Step-1: Find probability for a not red ball.}}$$
$${\text{Red ball =1, Black ball=1, Green ball=1.}}$$
$${\text{Total balls in bag=3.}}$$
$${\text{Let P be the probability of getting a not red ball.}}$$
$$\text{Probability=}\dfrac{\text{No. of outcomes(Black and Green)}}{\text{Total no. of outcomes}}$$
$$\text{Probability=}\dfrac{2}{3}$$
$${\textbf{Hence, probability of getting red ball is}}$$ $${\mathbf{\dfrac{2}{3}.}}$$
