How many strings are there of four lower case letters that have the letter x in them?
264 - 254 = 66,351
You have 26 letters in the alphabet.
Since it is a four-letter string, then the total amount of four-letter strings possible would be 26 x 26 x 26 x 26 = 264 = 456,976.
If we take out the amount of strings that have the letter "x" in them, we would be left with 25 letters in the alphabet, and like above, the number of four-letter strings without the letter "x" would be 25 x 25 x 25 x 25 = 254 = 390,625.
When you subtract the number of strings that do not have "x" in it to the total number of strings possible, then you would be left with the number of strings that DO have the letter "x" in them.
Thus 264 - 254 = 456,976 - 390,625 = 66,351
