How many 8-bit strings contain 7 or more 1's
WebThere is one byte (0) with no 1s. There are 8 bytes (1, 2, 4, 8, 16, 32, 64, 128) with one 1. All the rest must have at least two 1s. So the answer is 256 - 9 = 247. 15. Quora User. Studied … WebBits 7 and 8 are chosen in 0,1, and therefore there are 22 such strings. If p starts in position 3, the rst bit can be 0 or 1, then bit 2 is 1, bits 3-6 are 0 and bit 7 is 1. Bit 8 is chosen in 0,1. There are therefore 22 such strings. if p starts in position 4, each of the rst two bits is chosen in 0,1, then bit 3 is 1, bits 4-7 are 0 and bit ...
