Question

which of the following cannot be a probability of an event ? a 2/3,b -1.5,c 15%,d 0.7

Answer 1

The answer is B.

The probability of an event can never be below zero, the lowest chance of probability would be 0.

Answer 2

Answer:

Option b cannot be a probability of an event.

Step-by-step explanation:

Given some probabilities of an event we have to tell which cannot be a probability of an event.

The given probabilities of an event are $\frac{2}{3}, -1.5, 15\%, 0.7$

As we know the probability of any event lies between 0 and 1. It can never be negative nor greater than 1.

Hence, -1.5 is negative.

∴ Option b cannot be a probability of an event.
