Furthermore, each license plate string must contain exactly 8 distinct characters (including the space character). for example, cmsc250 is not a valid license plate string, but ’cm8z 2s0’ and ’bigcarsz’ are. how many license plate strings are possible?

  1,556,675,366,400

Step-by-step explanation:

There are 37 possible characters, of which 8 can be chosen. Order matters, so the number is ...

  37P8 = 1,556,675,366,400

This number includes 84,144,614,400 strings in which the space character is either first or last. Such strings may be ruled invalid because they are indistinguishable from 7-character strings.

nPk = n!/(n-k)! . . . . the number of permutations of n things taken k at a time

The 37 allowed characters are the 26 letters of the alphabet, 10 digits, and 1 space character.
