In a certain mathematics class, the probabilities have been empirically determined for various numbers of absentees on any given day. These values are shown in the table below. Find the expected number of absentees on a given day. Number absent Probability 5 6 01 2 3 4 0.01 0.08 0.12 0.24 0.35 0.14 0.06. The expected number of absentees on a given day is (Round to two decimal places as needed.)

16% of all Americans live in poverty. If 31 Americans are randomly selected, find the following probabilities. Round answers to 4 decimal places. a. Probability that exactly 4 of them live in poverty. b. Probability that at most 7 of them live in poverty. c. Probability that at least 5 of them live in poverty. d. Probability that between 1 and 6 (including 1 and 6) of them

According to the recent report, scientists in New England say they have identified a set of genetic variants that predicts extreme longevity with 77% accuracy. Assume 150 patients decide to get their genome sequenced. If the claim by scientists is accurate, what is the probability that fewer than 70% of the patientswill get a correct diagnosis for extreme longevity? Group of answer choices A. 0.1422 B. 0.0722 C. 0.2214 D. 0.0208

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 to know how to calculate using a TI-84 Plus calculator

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.
