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
(type an integer or a decimal. do not round.)

Explanation:

Step1: Recall Probability Formula

Probability is the number of favorable outcomes divided by the total number of possible outcomes. Here, favorable outcomes (last digit is zero) is 1, total outcomes (digits 0 - 9) is 10.

Step2: Calculate Probability

Using the formula \( P = \frac{\text{favorable}}{\text{total}} \), we get \( P=\frac{1}{10}=0.1 \).

Answer:

0.1
