Abram Kramer · Answer 1

The answer is A. The school play opens tonight and it is raining.

Chanel Werner · Answer 2

Events are said to be independent when the occurrence of one has no effect on the probability of occurrence of the other. If we look at choice A, the events 'school play opens tonight' and 'it is raining', the occurrence of rain does not affect the fact that the school play opens; also the opening of the school play did not alter the probability of rain.

With choices B, C and D, the probability of one of the events is affected by the occurrence of the other event.

Therefore the correct choice is A.
