If there is a 30% chance of rain on Sunday, what is the probability of no rain on Sunday?

The events "rain" and "no rain" are mutually exclusive, so P(rain) + P(not rain)=1
P(rain)=0.3
P(not rain)=1-0.3=0.7
There is a 70% chance it will not rain on Saturday

I like your setup and reply here. Cool. [tex]\lim_{x \to 0}x[/tex]

That limit expression evaluates to 0

The limit in my reply is a typo.
