A lock is using 3 digits from 1 to 7 as its lock combination, the numbers can be repeated. How many different possible lock comb
Oksi-84 [34.3K]

The question is an illustration of selection (or combination)

The number of lock combination is 343

The given parameters are:

<em />n = 7<em> --- the number of digits to select from</em>

<em />r = 3<em> --- the number of digits the lock uses</em>

<em />

Because the digits can be repeated, the number of lock combinations is:

Lock = n^r

So, we have:

Lock = 7^3

Lock = 343

Hence, the number of lock combination is 343
