The total snowfall per year in laytonville is normally distributed with mean 99 inches and standard deviation 14 inches. based on the empirical rule, what is the probability that in a randomly selected year, the snowfall was less than 127 inches

Required probability is 0.9772.

Step-by-step explanation:

Since we have given that

Mean = 99 inches

Standard deviation = 14 inches

It is normally distributed.

We need to find the probability that in a randomly selected year, the snowfall was less than 127 inches.

As we know that

So, it becomes,

Hence, required probability is 0.9772.
