Solution
\[\text{ Let A be the event of raining tomorrow } . \]
\[\text{ The probability that it will rain tomorrow, P\left( A \right), is 0 . 85 } . \]
\[\text{ Since the event of raining tomorrow and not raining tomorrow are complementary to each other, the probability of not raining tomorrow is }: \]
\[P\left( A \right) = 1 - P\left( A \right) = 1 - 0 . 85 = 0 . 15\]
