Question

a research center poll showed that 75% of people believe that it is morally wrong to not report all income on tax returns. what is the probability that someone does not have this belief?

the probability that someone does not believe that it is morally wrong to not report all income on tax returns is
(type an integer or a decimal.)

Explanation:

Step1: Understand the total probability

The total probability of all possible outcomes is 1 (or 100%).

Step2: Calculate the probability of the complement event

Let \( P(\text{believe}) = 0.75 \). The probability of not believing, \( P(\text{not believe}) \), is the complement of \( P(\text{believe}) \). So we use the formula \( P(\text{not believe}) = 1 - P(\text{believe}) \).
Substituting the value, we get \( P(\text{not believe}) = 1 - 0.75 = 0.25 \).

Answer:

0.25
