Question

express the indicated degree of likelihood as a probability value between 0 and 1. when using a computer to randomly generate the last digit of a phone number to be called for a survey, there is 1 chance in 10 that the last digit is zero. the probability is \square (type an integer or a decimal. do not round.)

Explanation:

Step1: Understand the probability

The problem states there is 1 chance in 10 that the last digit is zero. Probability is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Step2: Calculate the probability

The number of favorable outcomes (last digit is zero) is 1, and the total number of possible outcomes (digits 0 - 9) is 10. So the probability is $\frac{1}{10}$.

Step3: Convert to decimal

$\frac{1}{10} = 0.1$

Answer:

0.1
