Solution

Available alphanumeric letters are 26 + 10 = 36

For password order also matters i.e. abc is different from bca

Hence no of ways to select 3 = 36P3 = 36(35)(34) =42840

----------------------------------------------

If O and zero are avoided then no of ways

= 34P3 = 34(33)(32)=35904

-------------------------------------------------------

First letter can be any one of 2.

Second number can be any one out of 4.

Hence total permits = 2(4) = 8

-----------------------------

A to J there are 10 letters and 2 to 6 there are 5 numbers

Totally available = 15

No of passwords without repititions = 15P8 =

with repititions = 15^8=
