- 0.12
- 0.1
- 1.0
- 0.7
Show answer and solution
Correct answer: D. 0.7
For mutually exclusive events, P(A∪B) = P(A)+P(B) = 0.3+0.4 = 0.7.

Worked practice questions
A feasible region that extends indefinitely in some direction is said to be:
- convex only
- empty
- bounded
- unbounded
Show answer and solution
Correct answer: D. unbounded
A feasible region not enclosed within a finite boundary is unbounded.
The midpoint of the segment joining $(2,3)$ and $(4,7)$ is:
- (6, 10)
- (1, 2)
- (2, 4)
- (3, 5)
Show answer and solution
Correct answer: D. (3, 5)
((2+4)/2, (3+7)/2) = (3,5).
