Question

in how many ways we can select 3 from like groups of 11 persons?​

Answer 1

Answer:

165

Step-by-step explanation:

11 people can be picked first then 10 second and 9 third so we multiply these to find out how many ways we can organise 3 people picked but since there are 6 ways to organise them we must divide the answer by 6 so we get 11x10x9/6 as our answer which = 165
