Answer 1

Answer:

7/25

Step-by-step explanation:

Let the number of blue balls be 'x' and number of red balls be 'y'.

Given that number of white balls is 11 times number of blue balls.

So, the number of white balls = 11x.

Hence, the total number of blue balls and white balls = 12x.

Given that number of red balls is less than white balls and greater than blue

⇒ x < y < 11x

(i) When x = 1:

Number of blue balls = 1.

Number of white balls = 11

Number of red balls = (50 - 12) = 38

Here, red balls > White balls.

∴ Condition is not satisfied.

(ii) When x = 2:

Number of blue balls = 2.

Number of white balls = 22.

Number of red balls = (50 - 24) = 26.

Here, Red balls > white balls.

∴ Condition is not satisfied.

(iii) When x = 3:

Number of blue balls = 3

Number of white balls = 33.

Number of red balls = (50 - 36) = 14.

Here, Red balls < White balls.

∴ Condition is satisfied.

Hence:

It will be 3 < 14 < 33.

Total number of balls = 50.

P(getting a red ball) = 14/50 = 7/25.
