Question

A bag contains 6 red balls,8 blue balls and 10 yellow balls, all the balls being of the same size
If a ball is drawn from the bag, without looking into it, find the probability
that the ball drawn is :
(i) yellow (ii) red
(iii) blue (iv) not yellow (v) not blue.

Answer 1

Answer:

Total numbers of balls bag contains:

6 + 8 + 10 = 24.

(i)Probability of getting a yellow ball :-

P (E) = Numbers of yellow balls contains in bag / Total number of balls bag contains

P (E) = 10/24 = 5/12

(ii) Probability of getting a red ball :-

P (E) = Numbers of red balls contains in bag/ Total number of balls bag contains

P (E) = 6/24 = 1/4

(iii) Probability of getting a blue ball :-

P (E) = Numbers of blue balls contains in bag / Total number of balls bag contains

P (E) = 8/24 = 1/3

(iv) Probability of getting not a yellow balls:-

P (E) = Numbers of not a yellow balls contains in bag / Total number of balls bag contains

P (E) = 14/24 = 7/12

(v) Probability of getting not a blue ball :-

P (E) = Numbers of not a blue balls contains in bag / Total numbers of balls bag contains

P (E) = 16/24 = 2/3
