12 In order to ensure the safety of school classrooms the local Fire Marshall does an inspection at Southeast High School every month, looking for faulty wiring, overloaded circuits, etc. At SHS the new STEM Wing has 18 math rooms (including a state-of-the-art Statistics classroom), 14 science rooms, ar 4 Engineering & Technology rooms. The science rooms are divided into 6 biology, 4 physics and 4 chemistry rooms. Each month, the Fire Marshall randomly picks one of the rooms in the new wing to inspect each month. Define the following events: S=the event the selected room is a Science room B = the event the selected room is a Biology room C= the event the selected room is a Chemistry room P the event the selected room is a Physics room M= the event the selected room is a Math room St the event the selected room is a beautiful state-of-the-art Statistics room ET the event the selected room is an Engineering or Tech room Calculate the probabilities of the events described below P(S) = P(St or P) = P(B | S) =D P(M n not St) =
