Explanation / Answer

we have given reading of thermometer is normally distributed with mean 0 and standard deviation 1.

and find the probability that randomly selected thermometer reads greater than 2.09

that is Pr ( Z > 2.09) but we have given normal probability table of left side. So

Pr ( Z > 2.09) = 1 - Pr ( Z < 2.09) = 1 - 0.9817 ( calculated by given table take cross section of 2 and 0.09)

                       = 0.0183

Option C is correct answer.
