Question: A bit string is a string of bits (0’s and 1’s). The length of a bit string is the number of bits in the string. An example, of a bit string of length four is 0010. An example, of a bit string of length five is 11010. Use the Rule of Products to determine the following:

(a) How many bit strings are there of length eight? Explain

(b) How many bit strings are there of length eight which begin with a 1 and end with a 0? Explain
