Question 4

Question. 4

Which of the following cannot be the probability of an event?

(A) \(\dfrac{2}{3}\)    (B) −1.5    (C) 15%    (D) 0.7

Answer:

(B) −1.5

Detailed Answer with Explanation:

Probabilities must lie between 0 and 1 (inclusive). The number −1.5 is negative, so it cannot be a probability. The others (\(\dfrac{2}{3}\), 15% = 0.15, and 0.7) all lie between 0 and 1.
