##### A bag contains 5 white, 6 red and 4 green balls. One ball is drawn at random. What is the probability that the ball drawn is (i) green?(ii) white? (iii)non-red?

(i).

Total number of balls bag containing is: 5 white + 6 red + 4 green = 15 balls

Number of green balls = 4.

Probability P() =

Probability of getting a Green ball P(G) = =

(ii).

Total number of balls bag containing is: 5 white + 6 red + 4 green = 15 balls

Number of white balls = 5.

Probability P() =

Probability of getting a white ball P(W) = = =

(iii).

Total number of balls bag containing is: 5 white + 6 red + 4 green = 15 balls

Number of outcomes (No Red) = 5 + 4 = 9, that is 5 white balls + 4 Green balls.

Probability P() =

Probability of getting a Green ball P(G) = = =
