Web(c) How many bit strings of length seven contain two consecutive 0s? Solution. (a) Let a n denote the number of bit strings of length n that contain a pair of consecutive 0s. If a string of length n ends with 1 and contains a pair of consecutive 0s, then such a pair should be somewhere inside of the first n − 1 positions, so that we have a n−1 WebQ : Answer the following short questions. a) How many bit strings of length 10 contain exactly four 1’s? b) How many bit strings of length 10 contain at most four 1’s? c) A coin is flipped 10 times where each flip comes up either heads or tails.

WebTo find the number of 5-bit strings is straight forward. We have 5 bits, and each can either be a 0 or a 1. So there are 2 choices for the first bit, 2 choices for the second, and so on. By the multiplicative principle, there are 2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 = 2 5 = 32 such strings. 🔗 Finding the number of 5-bit strings of weight 3 is harder. Web(a) Find a recurrence relation for the number of bit strings of length n that contain a pair of consecutive 0s. (i) Step 1: write down a n (The goal: function of n). a n = (ii) Step 2: Find the relationship of a n with a n-1 and a n-2 ( and a n-3 …). (Use relationship of problem with sub-problems).
