Probability of No Rain

There is a 30% chance of rain tomorrow. What is the probability of no rain tomorrow?

P(no rain tomorrow) = 1 - P(rain tomorrow).

This yields the answer of something different happening next time.

IN GENERAL:

P(something not happening tomorrow or next time) = 1 - P(something happening tomorrow or next).

Pretty cool, right?

Re: Probability of No Rain

Yes. It follows from the following

If one of n events must occur then

P(event 1) + P(event 2) + ... + P(event n) = 1
