Using a binomial distribution considering there's a 30% chance it will rain on any of the three days:

The probability of it raining on 0 days is (1) (0.7) (0.7) (0.7) = 34.3%.

The probability of it raining on 1 day is (3) (0.3) (0.7) (0.7) = 44.1%.

The probability of it raining on 2 days is (3) (0.3) (0.3) (0.7) = 18.9%.

The probability of it raining on 3 days is (1) (0.3) (0.3) (0.3) = 2.7%.

There's a 65.7% chance that it will rain at least once over the three-day period.
