A bag conta

Answer :

Given:


Bag A contains 4 white balls and 2 black balls


Bag B contains 3 white balls and 5 black balls


It is told that one ball is drawn is drawn from is each bag.


Let us find the Probability of drawing each colour ball from the bag.


P(B1) = P(drawing black ball from bag A)





P(W1) = P(drawing white ball from bag A)





P(B2) = P(drawing black ball from bag B)





P(W2) = P(drawing white ball from bag B)





We need to find:


i. P(DWW) = P(Both are white)


ii. P(DBB) = P(Both are black)


iii. P(DWB) = P(One drawn is white and other is black)


P(DWW) = P(Both are White)


Since drawing a ball is independent for each bag, the probabilities multiply each other.





P(DBB) = P(Both balls are black)


Since drawing a ball is independent for each bag, the probabilities multiply each other.





P(DWB) = P(One ball drawn is white and other is black)


Since drawing a ball is independent for each bag, the probabilities multiply each other.





.


The required probabilities are .
