Answer:
7,077,888
Step-by-step explanation:
Of the 3 numbers, we can have 8 numbers in each position (since 0 and 2 are not allowed from the number 0 - 9 [10 digits]).
So that would be 8 * 8 * 8 different possibilities
Now,
we can have 24 letters in each position (since 0 and z are not allowed form the alphabets a - z [26 letters]).
So that would be 24 * 24 * 24 different possibilities
The number of passwords possible would be:
8 * 8 * 8 * 24 * 24 * 24 = 7,077,888
