Jessica tipped the driver about $4.75 or $4.756
If this is an option, it should be Similar Triangles.
You have to guess the first 5 digits.
You can calcualte the number of possible numbers that exist with 5 digits.
The first digit cannot be 0, it can be any from 1 to 9, so those are 9 diferent digits.
For the second, third, fourth and fifth digits there are 10 diferent posibilities for each: 0 through 9.
Then, there are 9*10*10*10*10 = 90,000 different possible social security numbers once the last four digits are known.
And the probability to get the correct social security number of the person is 1 /90,000 = 0,000011.
