When you enter at an establishment like KCC, your temperature will be checked before you are allowed to enter. The temperature outside is usually hot and there is a 30% chance that your temperature upon checking will be higher than the normal body temperature. If your temperature is higher than normal, the temperature scanner used by the security guard will have a 90% probability of detecting your high temperature. If your temperature is normal or below normal, the temperature scanner will have a 0% probability of registering a high temperature. If the temperature scanner registered a normal temperature, what is the probability that you have a body temperature higher than normal? Give your answer in four decimal places.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
