Outside a home there is a keypad that will open the garage if the correct six-digit code is entered. How many codes are possible?
Homework Answers
In a keypad, there are 10 numbers. Since the correct code is 6 digits, there are 6 positions have to be filled out of 10 numbers. Since, it is not given anything about repetition , I assume that repetition is allowed.
Therefore any number from 0-9 can come in any of the 6 positions, the number of codes possible is
10x10x10x10x10x10=
ways.

tavr 250 mg 1 tablet X 500 mg Many garage doors have remote-access keypads outside the door. Let's suppose a thiet approaches a particular garage and notices that four particular numbers are well-used. If we assume the code uses all four numbers exactly once, how many 4-digit codes does the thief have to try?
