- You have u= x^(1/2) with x0= $10,000. You can keep this10,000 and gain u = 100 or participate in a game. In this gamble, you can buy a lottery ticket. You might win a prize of 4 million. Lottery operators tell you that there will be N tickets sold. Your chances of winning are π = 1/N. What is the largest number of tickets N that would make you play this game? Briefly explain why N is such a small number. No diagram required.The mean number of patients admitted per day to the emergency room of a small hospital is 2.5. If, on any given day, there are only 3 beds available for new patients, what is the probability that the hospital will not have enough beds to accommodate its newly admitted patients? P(Y > 1 (formula) (numeric result) Use: y for the value of the variable ) for fractions ( )! for factorial ) for the exponential function e^( Note: You can earn partial credit on this problem."There is an average of four accidents per month at an intersection.
