							without replacement means you dont put back the ball that is drawn

1/3 is prob for selection of bag A
2/3 for bg B

red from bag A = 6/10

black from B = 7/10

selecting red from A = (1/3)*(6/10):

similarly, proceed for rest cases arrange using set theory and solve
revert if the problem persists
