Let A be the set of all bit strings of length 10. 1. How many bit strings of length 10 are there? How many bit strings of length 10 begin with 1101? How many bit strings of length 10 have exactly six 0's? How many bit strings of length 10 have equal numbers of O's and 1's? How many bit strings of length 10 have more O's than 1's? a. b. c. d. e.
4. [6 marks] (Basic Counting) How many bit strings of length 10 contain either five consecutive 0s or five consecutive 1s?
How many bit strings of length n are palindromes? Hint: Consider two cases n is even and n is odd. Note a palindrome is a “string” of letters or numbers which read the same “frontwards” and backwards”. Examples: 1101011, 10111101 are palindromes.
Exercise 8.12.20: Counting binary strings. (a) How many binary strings of length 12 do not have exactly four 1's? (b) How many binary strings of length 12 start with 101 or 1110? (e) How many binary strings of length 12 start with 00 or end with 00 or both?
How do I design a Turing Machine which accepts strings that begin with 'a' and end with two 'b's. For example, the strings abb and aaabb should be accepted. While the strings bbaa and ab should not be accepted.
How many 10-letter “words” using the 26-letter alphabet either begin or end with a vowel? Draw and use a Venn diagram to support your solution. Be sure to clearly identify your sets. (Letters may be repeated in this problem)
