Question

Determine whether the number could be the probability of an event. Explain your reasoning. − 0 . 25

Answer 1

So the answer is NO, the probability of an event cannot be -0.25.

Explanation:

i) The probability or likelihood of an event cannot be negative or less than zero.

ii) The probability of an event cannot be greater than 1.

iii) If the probability of an event is 0 then the event did not or does not happen

iv) If the probability of an event is one then the event did or does happen with 100% certainty.

v) If the probability is between 0 and 1 then the event occurs wit a certainty that is less than 100%.

vi) So the answer is NO, the probability of an event cannot be -0.25.
