A committee of 6 is to be chosen from 10 persons with the condition that if a particular person 'A' is chosen, then another particular person B must be chosen
Text Solution
Verified by ExpertsThe correct answer is:
154
(154)
Sol. If ‘A’ is not chosen, then number of selections = 9 C 6
If ‘A’ is chosen, then ‘B’ is also chosen, then number of selection = 8 C 4
∴ number of ways = 9 C 6 + 8 C 4 = 154
