Question

Represent the given set in Roster form.

A = {x: x is a prime number, $\frac{5}{2}$ < x < $\frac{11}{2}$}

• A. {-3,-2,-1, 0, 1, 2, 3, 4, 5}
• B. {-1, 0, 1, 2, 3, 4, 5,6}
• C. {-1, 0, 1, 2, 3, 4, 5}
• D. {-2,-1, 0, 1, 2, 3, 4, 5}

Answer 1

The correct option is D

{-2,-1, 0, 1, 2, 3, 4, 5}

$\frac{5}{2}$= 2.5

$\frac{11}{2}$ = 5.5

All prime numbers between 2.5 & 5.5 are {3, 5}
