Q. Which number represents the probability of an event that is certain to occur?

\newline

\frac{39}{20}

\newline

1

\newline

\frac{1}{100}

\newline

\frac{83}{100}

Understand Probability Concept: Understand the concept of probability for certain events. $\newline$ The probability of an event that is certain to occur is always $1$ . This is because probability is a measure of how likely an event is to occur, and if an event is certain, it has a $100\%$ chance of happening.
Evaluate Given Options: Evaluate the given options to find the probability of $1$ . The first option is $(39)/(20)$ , which is greater than $1$ , so it cannot represent a probability of a certain event. The second option is $1$ , which is exactly the probability of a certain event. The third option is $(1)/(100)$ , which is less than $1$ , so it cannot represent a probability of a certain event. The fourth option is $(83)/(100)$ , which is also less than $1$ , so it cannot represent a probability of a certain event.
Identify Correct Option: Identify the correct option that represents the probability of a certain event. From the evaluation in Step $2$ , the only option that represents the probability of a certain event is $1$ .
