Bag I contains 3 black and 2 white balls , bag II contains 2 black and 4 white
balls. A bag is selected and then a ball is drawn at random from selected
bag . Find the probability that selected ball is black ball.

Answer 1

total no. of ball in bag A=5

no. of black ball in bag A=3

therefore, P(getting black ball) =3/5

Answer 2

Answer:

From bag 1,

The probability of getting a black ball is...

3/5

From bag 2,

The probability of getting a black ball is...

2/6 = 1/3

The probability of getting black ball from random bags will be...

3/5 + 1/3

2

Therefore it will be 7/15...
