Quizplus · Accepted Answer

The correct notation for representing the event that the absolute value of the difference of the two numbers is 2 is $\{ X = 2 \}$. This notation directly specifies the event of interest in terms of the random variable $X$.

Use Random-Variable Notation to Represent the Event {X=2}\{ X = 2 \}{X=2}
