Answer:

C. the probability of it not happening is 0.3.

Step-by-step explanation:

Probability of event happening is of 0.7.

Either it happens, or it does not. The sum of these probabilities is 100%.

0.7 probability of happening, so 1 - 0.7 = 0.3 probability of not happening, and the correct answer is given by option C.

A is wrong as the probability is not 1, and B is wrong as the probability is higher than 0.5.
