Question 202590
<font face="Garamond" size="+2">


There are 26 letters in the alphabet.  Leaving out I and O, that leaves 24 letters from which to choose.  Once you have chosen the first letter, there are 10,000 ways to chose the 4 digits if you allow 0000.  Then once you have chosen the first letter and the 4 digits, there are 23 letters to choose from since you cannot repeat the first letter, so in total:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 24\ \times\ 10000\ \times\ 23]


You can do your own arithmetic. The easy way is to multiply 24 times 23 and then tack four zeros on the end of your answer.
