WebThere are 26 strings of length 6; 25 of length 5; etc. down to 20 strings of length 0 (that’s the empty string). So, alto-gether, that gives 26 + 25 + 24 + 23 + 22 + 2 + 1 = 27 1 = 127 bit strings altogether. 16. How many strings are there of four lowercase letters that have the letter x in them?
