Question

there are 5 balls in a vessel out of two are red two are blue and one is green when a ball is selected at random then probability that the ball is not a red ball ​

Answer 1

Given:

Total number of balls in a vessel = 5

Number of red balls = 2

Number of blue balls = 2

Number of green balls = 1

Probability of an event=$\frac{Number of favorable outcomes}{Total number of outcomes}$

Here; number of favorable outcomes = 5, and total number of outcomes = 5-2 = 3

Therefore, probability of getting a ball which is not red = $\frac{3}{5}$
