Answer: The probability that a randomly selected citizen has a favorable or unfavorable opinion is 1 or 100%.

In this question, we have only two answers favorable or unfavorable.

A person can't have both opinions at the same time.

So these events - favorable and unfavorable are mutually exclusive events i.e one event cannot occur when the other occurs.

Let P(F) be the probability of a person who has a favorable opinion

P(UF) be the probability of a person who has an unfavorable opinion

\boldsymbol{\mathbf{P(F) = \frac{Total people with favorable responses}{Total people in the survey}}}

\boldsymbol{\mathbf{P(F) = \frac{62}{100}}}

\boldsymbol{\mathbf{P(UF) = \frac{No. of people with unfavorable opinion}{Total number of people in the survey}}}

\boldsymbol{\mathbf{P(UF) = \frac{38}{100}}}

Now, the probability of either one of two mutually exclusive events occurring is:

\boldsymbol{\mathbf{P(F or UF) = P(F) + P(UF)}}

\boldsymbol{\mathbf{P(F or UF) = \frac{62}{100} + \frac{38}{100} = \frac{100}{100}=1}}

However, if you need the money sooner for a car you should only take on a minimal amount of risk.
