A. probability of −2 indicates an event will definitely happen.
B.A probability of 12 indicates an event is neither likely nor unlikely to happen.
C.A probability of 910 indicates an event is unlikely to happen.
D.A probability of 1 indicates an event will definitely not happen.

Answer 1

B.

Explanation:

I assume the middle two choices have fractions 1/2 and 9/10.

In probability, 1 means it will definitely happen. 0 means it will definitely not happen.

1/2 means it is as likely to happen as it is to not happen.

Answer: B.

Answer 2

do not think any are true

Explanation:

a probability of zero means it can never happen

a probability of one means it will always happen
