when we solve the above it should be (4/10)*(3/9)*(6/8)*(5/7)=1/14 which is not even present in the option.Plzz explain.
Hi,
you assume it is blue blue green green, but there are 5 other possible orders:
bgbg
bggb
gbgb
ggbb
gbbg
You can observe, though, that the probabilities of these orders appearing are equal, hence you can arrive at the correct answer by multiplying 1/14 by 6.
Hence option C is correct.
