Answer:

The claim cannot be true because any probability is between 0 and 1.

Step-by-step explanation:

4 times 0.30 is 1.20, a value that cannot be a probability. Any probability will be between 0 and 1 (inclusive).

The claim cannot be true because any probability is between 0 and 1.

The claim cannot be true because any probability is between 0 and 1.

If he's saying that tomorrow you have 4 times the probability of today, which is 30%, that would be 120%. But you can't be 120% sure that it will rain.
