Which number is not included in the interval [-3, 2)?
Answer and explanation
Correct answer: 2
The interval [-3, 2) includes -3 because the left square bracket indicates inclusion. It contains every real number greater than -3 and less than 2. The right parenthesis excludes 2, so 2 is not part of the interval. The other choices, -3, 0, and 1.5, all lie within the included range and are therefore members of the interval.
