False; the "or" is an additive property so the probability of rain or snow muse be greater than or equal to 0.65.
"There is a high probability of rain this evening."
If the probability that it will rain is 0.25, then the probability that it is sunny is 0.75. The probability of it being sunny for five days, then is 0.755, or about 0.2373.

No, it means it might, with a probability of 0.1
IF probability of rain is X percent then probability of no rain is 100- X percent. For example if prob of rain is 80% prob of no rain is 20%
LetA= rainP(A)=0.38LetA'= not rainP(A') =1 - P(A)=1 - 0.38=0.62so probability of it will not rain tommrow is 0.62

This is a binomial probability distribution; n=12, r=2 & P=.05. Read directly from the table probability of 2 is .099 (plugging this data into my calculator gives 0.09879).
No, it means it might, with a probability of 0.1
There is a 70% chance it will not rain tommorrow! There is a 70% chance it will not rain tommorrow!
Certain.
It means how likely is it to rain.
