Answer:
32
Step-by-step explanation:
Let the number of black balls in the bag be 'x'.
Given that there are 8 white balls in the bag.
So, the total number of balls = 8 + x.
Now,
Given that probability of drawing a black ball is 4 times that of white ball.
P(Drawing a black ball) = P(Drawing a white ball)
⇒ (x/8 + x) = 4(8/8 + x)
⇒ x = 32.
Therefore, The total number of black balls in the bag is 32.
Hope it helps!
