Question

The lock is numbered from 0 to 49. Each combination uses three numbers in a right, left, right pattern. Find the total number of possible combinations for the lock.

Answer 1

50 (because 49 and 0)
put to the 3ed power because combination uses 3 numbers
50.3 (50 to the 3ed power)
50×50×50=125,000

So the answer is 125,000 different combinations.
