@Vivek Bag1 contains 1/2red and bag 2 contains twice of Bag1 so 2*1/2and 1/4th of red balls in bag 2. So 2*1/2*1/4=1/4. Then 1/2+1/4=3/4.

If we get 1 balls that is the total of 14 balls and 1 combination that means 14c1 = 14.

By the complement rule.
P(W) = 1-P(B).
= 1 = 6/14 = 4/7.
P(W) = 1-P(B).
= 1 = 6/14 = 4/7.
