Question

the two bag A and B contain 2 white, 4 black ; and 3 white, 3 red bolls respectively one of the bag is selected at random at a boll is drown from it. if the selected ball is of white colour, find the probability that is the drown from bag A​

Answer 1

Step-by-step explanation:

The probability of choosing a white ball from bag A is 1/3.

The probability of choosing a white ball from bag B is 1/2.

The probability of choosing either bags are 1/2 respectively.

Hence the probability of chosen white ball is from bag A is (1/2*1/3)/((1/2*1/3)+(1/2*1/2))

=2/5 2/5=0.4
