Assume the readings on thermometers are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degress C. Find the probability that a randomly selected thermometer reads between -2.21 and -1.52 and draw a switch then find the probability.

The standard normal distribution has a cumulative distribution function (probability that the random variable, in this case the temperature, is less than a given number) well-known as erf, and the probability of [tex]T\in[-2.21,-1.52][/tex] is [tex]erf(-1.52)-erf(-2.21)\approx 0.0298109[/tex] (found using WolframAlpha)
