So for example, a 3 digit hexadecimal number might be 2B8. How many 2-digit hexadecimals are there in which the first digit is E or F? Explain your answer in terms of the additive principle (using either events or sets). WebFinally, a bit string of length four that starts with 1 and ends with 00 will be of the form 1 ∗ 0 0, so there are 2 bit strings of this form. By the subtraction rule there are 2 3 + 2 2 − 2 = 8 + 4 − 2 = 10 possibilities. You Try If a card is drawn from a standard 52-card deck, how many ways can the card be black or a face card?
