The probability that a day requires more water than is stored in city reservoirs is 0.161.
Step-by-step explanation:
Given : Water use in the summer is normally distributed with
Standard deviation :
Let x be the combined storage capacity requires by the reservoir on a random day.
Z-score :
The probability that a day requires more water than is stored in city reservoirs is :
Hence, the probability that a day requires more water than is stored in city reservoirs is 0.161
