The probability that you have written the first 2 digits of your phone number is 1/90

How to determine the probability that you have written the first 2 digits of your phone number?

The number is given as:

0 - 9 i.e 10 digits

The selection is without replacement

This means that the first selection can be any of the 10 digits, while the second selection can be any of the remaining 9 digits

So, the number of selections is

Selection = 10 * 9

Evaluate

Selection = 90

The probability is represented as:

P = 1/Selection

This gives

P = 1/90

Hence, the probability that you have written the first 2 digits of your phone number is 1/90
