The solution and the answer by @richwmiller are totally W R O N G.
For your safety, simply ignore it.
Below please find the correct solution.
The problem says NOTHING about if repeating of symbols is allowed or not.
By DEFAULT, we must assume that repeating is allowed.
Then you have any of 26 letters of the English alphabet at the first position;
any of 10 digits at the positions from 2 to 4, and
any of 5 special symbols in positions 5 and 6.
In all, there are  = 650000 different possible passwords.
