"Assuming the daily rainfall in a certain city follows a normal distribution with a mean of 0.5 inches and a standard deviation of 0.2 inches, what is the probability that the total rainfall in 30 days exceeds 20 inches?"
Added by Joel W.
Step 1
We are given that the daily rainfall follows a normal distribution with a mean (μ) of 0.5 inches and a standard deviation (σ) of 0.2 inches. We want to find the probability that the total rainfall over 30 days exceeds 20 inches. Show more…

The next 10 days will have a 90% chance of rain. What is the probability that it rains every day for the next 10 days? What is the mean of rain for the next 10 days? What is the variance of rain for the next 10 days? What is the standard deviation of rain for the next 10 days?
