Question

In a bag contains red, white and black balls, the probability of taking out a white ball is half that of the black ball.
If there are 4 black balls and 20 balls in total, then what will be the total number of red balls?

Answer:

as there are 4 black balls

and white balls will be half of black as said in question.

white balls = 2

so

4+2+14=20
