Which of the following cannot be the probality of an event a)1/2 b) 10% c) 0.7. d) 3/2. which is the correct option with the solution

D

Step-by-step explanation:

In probability,

a probability of 0 means that it is IMPOSSIBLE, sure that this event WILL NOT occur, ever. So, probability of anything less than 0 is not possible.

On the other hand, probability of 1 means that it is CERTAIN to happen. So, probabilty of anything greater than 1 can't happen.

So we can say:

0 <= Probability of an Event happening <= 1

Option A is 1/2, which is in the middle, so this is OKAY.

Option B is 10%, which is certainly close to 0 and between 0 and 1, so this is OKAY.

Option C is 0.7, which is close to 1 and greater than 0, so in between 0 and 1, certainly. So this is OKAY.

Option D is 3/2 which is 1.5, so this is GREATER THAN 1, so it can't ever be possible.

Option D is the correct choice.
