Social Security Numbers A social security number consists of nine digits. How many different social security numbers are possible if repetition of digits is permitted?
There is a possibility of 10 numbers in each place. There are 9 places in a social security number (123456789)… 10^9=10x10x10x10x10x10x10x10x10=1 billion =1 billion combinations is this right????
