You are dialing a friends number and cant remember the last digit. If you choose a digit at a random, what is the probability that you dial the correct number?

Respuesta :

We know that the total number of digits is: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Therefore, total digits = 10

The probability that the number is dialed correctly is:

[tex]P=\frac{1}{10}=0.1[/tex]

Answer: The probability is 0.1
