: If you pick an answer to this question at random, what is the chance that you will be correct?

\newline

a)

25 \%

\newline

b)

60 \%

\newline

c)

50 \%

\newline

d)

25 \%

Count Total Possible Answers: Count the total number of possible answers. $\newline$ There are $4$ possible answers ( $a$ , $b$ , $c$ , $d$ ).
Identify Duplicate Options: Notice that options a) and d) are the same, both saying $25\%$ . This means there are actually only $3$ different possible answers.
Calculate Probability: Calculate the probability of choosing one correct answer out of the $3$ different possible answers. $\newline$ The probability would be $1$ out of $3$ , which is approximately $33.33\%$ .
