Answer:
There are 151,200 possible license plates.
Step-by-step explanation:
The order in which the digits are positioned is important(for example, 012345 is a different plate than 102345). No repeat digits are allowed, which means that we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
There are 10 possible digits(from 0 to 9).
The plate has 6 slots.
So
There are 151,200 possible license plates.
Additive inverse property : a + (-a) = 0
