Consider three classes (I, II and III) consisting of 30, 25, and 45 students. Suppose a student is selected from class I, then he has 10% chance to make an A. Assume that these probabilities for the class II and III are 15% and 20% respectively. If a student is selected randomly and has an A, what is the probability that he is from class III. Enter your answer to the nearest FOUR decimal places. 0.5715

I need help with developing the excel formula to calculate the probability for the 5th question of this assignemnt. In this tab, you must answer the five questions below the table of data. To do so, you will have to write formulas which calculate probabilities. To write these formulas, remember the following formula for classical probability: ?(?) = ?/ ? = ?????? ?? ???? ????? ? ?????? / ????? ?????? ?? ???????? ???????? ?? ?ℎ? ?????? ????? Each of the questions involves a different “X”, and some of them involve different “T”s. Think through each question carefully to make sure you identify these values correctly.
