Answer

Brief Explanations:

The complement of an event A is the event that A does not occur. The probability of an event and its complement sum to 1. Here, the event of rain and no - rain are complements. If the probability of rain is 30% (or 0.3), the probability of no - rain is 1 - 0.3=70% (or 0.7), which is based on the Complement Rule.

Answer:

D. Complement Rule
