Lot A consists of 3G and 2D articles. Lot B consists of 4G and 1D article A new lot C is formed by taking 3
articles from A and 2 from B. The probability that an article chosen at random from C is defective, is
i think there will be more cases
for example in 4G 1D
3G from first and 1G 1D from 2nd should also be counted
there will be so many cases
any other way to solve?
Only 6 cases
