A) 3700
B) 3720
C) 4340
D) None of these
Correct Answer: B
Solution :
At least one green ball can be selected out of 5 green balls in \[{{2}^{5}}-1\] \[i.e.\], in 31 ways. Similarly at least one blue ball can be selected from 4 blue balls in \[{{2}^{4}}-1=15\] ways. And at least one red or not red can be select in \[(n+1)\ !\] ways. Hence required number of ways = \[31\times 15\times 8=3720\].You need to login to perform this action.
