Hello, I am stuck at breaking down the equation to get the decimal for probability.

Police response time to an emergency call is the difference between the time the call is first received by the dispatcher and the time a patrol car radios that it has arrived at the scene. Over a long period of time, it has been determined that the police response time has a normal distribution with a mean of 11.6 minutes and a standard deviation of 2.3 minutes. For a randomly received emergency call, find the following probabilities. (For each answer, enter a number. Round your answers to four decimal places.) (a) the response time is between 7 and 13 minutes (b) the response time is less than 7 minutes (c) the response time is more than 13 minutes Need Help? Read It Submit
