Using Excel, A manufacturer of Celsius thermometers claims the thermometers they produce have an average (mean) reading of 0 degrees Celsius and a standard deviation of 1 degree Celsius for freezing water . If one of these thermometers is randomly selected, find the probability that, at the freezing point water, the reading is:

1. less than -1.2 degrees Celsius

2 no more than 1.2 degrees Celsius

3 greater than -0.2 degrees Celsius

4 at least 0.81 degrees Celsius

5 between -2.1 degrees Celsius and 0 degrees Celsius

6 between 0.55 degrees Celsius and 1.55 degrees Celsius

7 between -1.4 degrees and 1.4 degrees Celsius

8 less than -1.4 degrees Celsius or greater than 1.4 degrees Celsius

9 less than -1 degrees Celsius and greater than 1 degree Celsius

10 less than 0.75 degrees Celsius and greater than -0.75 degrees Celsius
