Question 1150269
A company places a 8-symbol code on each unit of product. The code
consists of 3 letters, the first of which is a vowel followed by 5 digits, the first and second of which are number 4 and 6. How many different codes are possible?
------------------------
The vowel is 1 of 5.
Letters 2 and 3 are 1 of 26 (assuming vowels can be used).
-----
The "4 and 6" are 1/1, unless you mean either 4 or 6.
The last 3 digits are each 1 of 10.
---> 5*26*26*1*1*10*10*10

Not a well stated problem.
