Question 412777

You don't even remotely know how to spell remotely -- you are in big trouble.


Since 0 and 9 are excluded from the first digit, there are 8 choices left.  For each of those 8 choices we can choose any digit we like for the second digit, so we have 10 choices.  8 times 10 is 80 possibilities for the first two digits.  For each of those 80 possibilities, we have 10 choices for the third digit: 800 choices.  And so on...


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 8\ \times\ 10\ \times\ 10\ \times\ 10\ \times\ 10\ \times\ 10]


gets you the number of choices for the first 6 digits.


Finally, you come to the last digit.  Greater than or equal to 4 and less than or equal to 5.  The last digit can either be 4 or 5, which is to say two choices.


Final tally:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 8\ \times\ 10\ \times\ 10\ \times\ 10\ \times\ 10\ \times\ 10\ \times\ 2]


You get to do your own arithmetic.
