Solution
Total number of memebers of a group = 10
We have to chose four members among the 10 people.
Total number of ways of selecting \'r\' people among the group of \'n\' people is given by a combination formula = nCr
Thus, Number of ways of selecting 4 people among 10 people = 10C4
Thus, Number of ways = 10!/(4!*6!) = 210
