An electrician is testing the accuracy of resistors that have a nominal resistance of 15 (ohms). He finds that the distribution of resistances is approximately normal with a mean of 15.08 and a standard deviation of 1.52. What is the probability that
a)a resistor selected randomly has a resistance less than 13 ?
b)a resistor selected randomly has a resistance greater than 14.5 ?
c)a resistor selected randomly has a resistance between 13.8 and 16.2 ?
