Two events are independent if the occurrence of one has absolutely no effect on the occurrence of the other. In this case, whether or not it rains today has no effect on the chance of rain tomorrow. Can you now see what the probability of rain tomorrow must be?
Hint: Express your answer as a decimal fraction, not as a percentage.
