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) = = =
