# Suppose that the temperature is normally distributed with expectation 50℃ and variance 4℃.What is the probability that the temperature T will be between 48℃ and 53℃?What is the probability that T≥52℃?

The probability that the temperature will be between

Main problem is that the standard deviation is the square root of the variance and it is expressed in the same units as the mean is, whereas the variance is expressed in squared units.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
