ways to select 4 persons from 10 persons = 10!/((6!)*(4!)= 210
ways to select 5 persons from 10 persons = 10!/((5!)*(5!)= 252
ways to select 6 persons from 10 persons = 10!/((6!)*(4!)= 210
ways to select 7 persons from 10 persons = 10!/((7!)*(3!)= 120
ways to select 8 persons from 10 persons = 10!/((8!)*(2!)= 45
ways to select 9 persons from 10 persons = 10!/((9!)*(1!)= 10
ways to select 4 persons from 10 persons = 1

ways to select 4 or more persons from 10 persons =
210+252+210+120+45+10+1 = 848 ways
