Which of the following cannot be the probability of an event?
A) 0.9
B) – 1.5
C) 10%
D) 2/5
Answered Feb 05, 2023
Correct option is (B) –1.5
\(0\leq P(E)\leq1\) for any event E.
It means probability of any event never be negative and never be greater than 1.
\(\therefore\) - 1.5 never be the probability of any event.
Correct option is B) – 1.5
Correct Answer - (i) 0 (ii) 1 (iii) 1-P(E) (iv) 1 (v) 0, 1
Correct option is (B) 1 The probability of a certain event is 1.
Correct option is (C) –0.2 \(\because\) For any event, \(0\leq P(A)\leq1\) Hence, probability of any event never be negative. Therefore, - 0.2 never be the probability of any event.
Correct option is (C) Certain event If the probability of an event is 1, then the event is called the certain event (or sure event).
Correct option is (D) 0 ≤ P ≤ 1 \(\because\) Probability of any event is always greater or equal to 0 and less than or equal to 1. i.e., 0 ≤ P ≤...
