Probability of Drawing White Ball
Bag A contains 9 white and 8 black balls, while bag B contains 6 white and 4 black balls. One ball is randomly picked up from the bag B and mixed up with the balls in the bag A. Then a ball is randomly drawn from the bag A. If the probability, that the ball drawn is white, is 
, gcd(p, q) = 1, then p + q is equal to
, gcd(p, q) = 1, then p + q is equal toSELECT ONE OPTION
