Probability question:

An electronic security gate is opened using a six-character code where the first two characters are letters from A to F and the last four characters are digits from 0 to 9. One such code is DF1269. How many different codes are possible?

Hey!

I think you do it like: 6 x 6 x 10 x 10 x 10 x 10

Therefore, there is 360 000 combinations.

Let me know if this is the right answer!

You can start from A to F with 0-9.
It will come just like :-  6 *6*10*10*10*10
Total combinations will be:-3,60,000.
