Ans:
Urn A: 4 white and 3 red marbles
Urn B: 2 white and 5 red marbles
Probability that a white marble is selected from Urn A=4/(4+3)=4/7
Probability that a white marble is selected from Urn B=2/(2+5)=2/7
As,both events are independent,so
Probability that the two marbles selected are white=(4/7)*(2/7)=8/49
