Question

A fair die is rolled once. The event set of getting a prime number is represented in which of the following way?

• A. $E=(2,3,5)$
• B. $E=\{2,3,5\}$
• C. $E=[1,2,3,5]$
• D. $E=\{1,2,3,5\}$

Answer 1

The correct option is B $E=\{2,3,5\}$

$1$ is neither a prime number nor a composite number.
The event set of any experiment is always represented in curly vraces '{ }'.
Hence, $E=\{2,3,5\}$
