We are organizing various historical artifacts in a museum. Each artifact gets a code consisting of two letters and one single digit number (0-9). For instance, KE4, YY6, AB3 are possible codes we could assign.
If we start by assigning codes at random, what is the probability that an artifact will have a code that includes the letter W and number 8?
I know 26x25 to get total outcomes = 650
I'm not sure what to do with the two alphabet letter places in which at least one has to be W
I know number 8 has to be chosen
