Probability of No Rain

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

Let me see.

I know that 30% = 0.30 as a decimal.

Let P = probability

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

P(no rain) = 1 - 0.30

P(no rain) = 0.70

P(no rain) = 70%

You say?

Re: Probability of No Rain

yes

I struggle greatly with probability problems. I hope to overcome this set back in my future self-study of basic probability.
