We usually write numbers in decimal form or base 10, meaning numbers are composed using 10 different "digits" {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. Sometimes though, it is useful to write numbers in hexadecimal or base 16. Now, there are 16 distinct digits that can be used to form numbers: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F}. So, for example, a 3-digit hexadecimal number might be 2B8. a. How many 4-digit hexadecimals are there in which the first digit is E or F? b. How many 6-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)? c. How many 5-digit hexadecimals start with a letter (A-F) or end with a numeral (0-9) (or both)?
