Question

A bag contains 20 black and 30 white balls. One ball is drawn at random. What is the probability
that the ball drawn is white​

Answer 1

Answer:

Total cases = 10 + 20 = 30

Favourable cases = 20

So probability = 20/30 = 2/3

black ball = 20

and ,

white ball = 30

so,.

total ball = 50.

now,

probability = fav. outcomes / total no. of outcomes.

then ,

probability of white ball = 30/50

or we can say ,

3/5.
