Guess that a person workout 6 days in a week. At each working days, he goes for either ‘A named Training ’ or ‘B named Training’. The probability that he chooses to train for "B named Training" on a single working day is 0.7. 1. Calculate the probability that exactly 5 of the 6 days he’ll go for "B named Training". 2. What is the probability that he trains for ‘A named Training’ at least twice in 6 days ? c. Find the EXPECTED number of "B named Training-days"
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…
