The characters are 0, 1, 2, 3, 4, 5, M, V, T, G, Y, or R. What is the total number of codes that can be randomly assigned?

you have 12 "digits" selected 5 at a time. The total number of codes available = 12^5 = 248832

Hi,
Since there are no restrictions on repeating characters, or on using numbers or letters in any particular spots in the codes, and there are 12 total number and letter choices for each spot in the codes, your answer can be calculated by finding 12^5. This is 248,832.
Hope this helps!
12 characters to choose from, 5 used in a code, and order matters,
12P5 = 12 • 11 • 10 • 9 • 8 = 95,040
