Answer: The two quantities are equal.
Step-by-step explanation:
Given that without even reading the questions, you guess on all four questions of a true-or-false test.
In Column A, Probability of choosing right answer will be
P(exactly one right answer) = 1/2
Number of right answers = 1/2 × 4 = 2
In Column B, Probability of choosing right answer will be
P(exactly one wrong answer) = 1/2
one wrong
Number of wrong answers = 1/2 × 4 = 2
Therefore, we conclude that the two quantities are equal.
