Consider strings of length n over the set {a, b, c, d}. a. How many such strings contain at least one pair of?
Consider strings of length n over the set {a, b, c, d}.
a. How many such strings contain at least one pair of consecutive characters that are the same?
b. If a string of length ten over {a, b, c, d} is chosen at random, what is the probability that it contains at least one pair of consecutive characters that are the same?
a. There are 4*3^(n-1) strings with no repeated characters, so there are 4^n-4*3^(n-1) strings with at least a double.
b. There are 4^n possible strings. So, the probability is (a) when n=10 divided by this total possible amount:
P=(4^n-4*3^(n-1))/4^n=1-(3/4)^(n-1)
=1-(3/4)^9
=0.924915314
Chance of getting a double.
