The shaded part of the number line in the given figure can also be described as

Question:

The shaded part of the number line in the given figure can also be described as

(a) (–∞, 1) ∪ (2, ∞)

(b) (–∞, 1] ∪ [2, ∞)

(c) (1, 2)

(d) [1, 2]

Solution:

Since shaded region does not include 1 and 2 but includes every value before 1 and every value after 2.

Hence, shaded region is given by (–∞, 1) ∪ (2, ∞)

Hence, the correct answer is option A.
