We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different "digits" {0,1,...,9}. Sometimes though it is useful to write numbers hexadecimal or base 16. Now there are 16 distinct digits that can be used to form numbers: {0,1,...,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? 8192 b. How many 5-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)? 245760 c. How many 3-digit hexadecimals start with a letter (A-F) or end with a numeral (0-9) (or both)? 2112
