WebHow many bit strings of length 10 contain a)exactly four 1s? This is just asking us to choose 4 out of 10 slots to place 1’s in. C(10;4) = 10!=(4! 6!) = (10 9 8 7)=4! = 210. b)at most four 1s? We add up the number of bit strings of length 10 that contain zero 1s, one 1, two 1s, three WebThese are the bit positions where the 0s go. There are C(10, 3) such 3-subsets. For each such 3-subset, all other positions take 1s. There is 1 way to do that. The answer thus is C(10, 3) = 10 . 9 . 8 / 3 . 2 . 1 = 120.
