Question

[1]. A bag contains four white and
two black balls and a second bag
contains three of each colour. A
bag is selected at random, and a
ball is then drawn at random from
the bag chosen. What is the
probability that the ball drawn is
white?​

Answer 1

Answer:

The no of white balls = 4

The no of black ball = 2

Three each colours of ball, thee are only 2 colours so there will be two balls of same colours

So, the white balls can be found from choosing the random bags = 4 + 2 [ Here it asked white balls so we calculated 2 balls from 2nd bag ]

The probability of white ball is = 6/9

Converting in simplest forms = 2/3 Ans.....
