Answer: 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.
28 is the correct answer.
