The probability that it will rain tomorrow is 0.3 . Part 1 of 2 (a) What is the probability that it won't rain tomorrow? \[ P \text { (it won't rain tomorrow })=0.7 \]

Step 1 ：The probability that it will rain tomorrow is 0.3.

Step 2 ：The probability that it won't rain tomorrow is 1 - the probability that it will rain tomorrow.

Step 3 ：So, the probability that it won't rain tomorrow is \(1 - 0.3 = 0.7\).

Step 4 ：Final Answer: \(P \text { (it won't rain tomorrow })=\boxed{0.7}\)
