2.A university professor noticed that students who attend classes regularly achieve better grades.He noticed that 45% of students who attend classes regularly achieve a grade of at least A-, while only 10% ofstudents who don't attend classes regularly achieve a grade of at least A-. About 65% of students attendclasses regularly.А.A student is randomly selected, what is the probability that they achieved a grade lower than A-?A students was selected and found to have gotten a grade of at least A-, what is the probability theyВ.attended class regularly?

Assume a Doctor uses a specific form of mesh to repair all hernias in his hernia patients.The makers of the mesh found there was an error that occured while making the mesh,and the hernia mesh has a 45% chance of failure. The doctor has treated 7 patients with the mesh so far;thus,the probability that the mesh does not fail in all seven patients is .0152. True or False

I bought the soundtrack to a movie that had a total of 14 tracks. After listening to all of the tracks, I found that I liked 4 of the tracks. With the random feature on my player, each of the 14 tracks is played once in random order. What is the probability that among the first two songs played I like neither one?

Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 43 passengers, and a flight has fuel and baggage that allows for a total passenger load of 7,181 Ib. The pilot 7,181 lb sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than - = 167 Ib. What is the probability that the aircraft is overloaded? Should the pilot take any action to correct for an 43 overloaded aircraft? Assume that weights of men are normally distributed with a mean of 178.9 lb and a standard deviation of 35.4. The probability is approximately (Round to four decimal places as needed.)

Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load passengers, and a flight has fuel and baggage that allows for a total passenger load of 5,670 lb. The pilot sees that the plane is full and all passengers are the aircraft. The aircraft can carry 35 5,670 lb men. The aircraft will be overloaded if the mean weight of the passengers is greater than = 162 lb. What is the probability that the aircraft is 35 overloaded? Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 182.8 lb and a standard deviation of 39.3. The probability is approximately. (Round to four decimal places as needed.) Should the pilot take any action to correct for an overloaded aircraft? O A. Yes. Because the probability is high, the pilot should take action by somehow reducing the weight of the aircraft. O B. No. Because the probability is high, the aircraft is safe to…
