At an ocean-side nuclear power plant,seawater is used as part of the cooling system.This raises the temperature of the water that is discharged back into the ocean.The amount that the water temperature is raised has a uniform distribution over the interval from 10 to 25ºC. Suppose that a temperature increase of more than 18ºC is considered to be potentially dangerous to the environment.What is the probability that at any point of time,the temperature increase is potentially dangerous?
A)0.47
B)0.72
C)0.28
D)0.50

Question

The probability that the temperature increase is potentially dangerous is the area under the uniform distribution curve between 18 and 25ºC. This area is equal to (25-18)/(25-10) = 0.47.
