Answer:
Option D
Step-by-step explanation:
Probability is the likelihood or chance of an event occurring.
Probability = the number of ways of achieving success
/the total number of possible outcomes
For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .
The probability of something which is certain to happen is 1.
The probability of something which is impossible to happen is 0.
The probability of something not happening is 1 minus the probability that it will happen.
By definition we can see that probability lies between 0 and 1 only both inclusive
Hence option D is right.
