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.
