Question

Please help! Will give fan and medal.

To create an entry code, you must choose 3 letters and then, 5 single-digit numbers. How many different entry codes can you create?

Thank you in advance! :)

Answer 1

heya
so split it into each letter or number, and work out how many combinations for each
then multiply out

Answer 2

Sorry, what? I don't understand.

Answer 3

example, if your code was 2 letters, then 2 numbers:
eg
AB12
split it
A = 26 letters in alphabet, so 26 possibilities
B = 26 letters in alphabet, so 26 possibilities
1 = 10 possible numbers, so 10 possibilities
2 = 10 possible numbers, so 10 possibilities

= 26 x 26 x 10 x 10

Answer 4

that make more sense?

Answer 5

Soooo, for mine it would be:

26*26*26*10*10*10*10*10 ?

Answer 6

perfect :)

Answer 7

And whatever those equal up to is the final answer? :)

Answer 8

yep, whatever that equals is the total number of combinations

Answer 9
