please answer the second question and last

Rick Wing, salesperson for Wave Soldering Systems, Inc. (WSSI), has provided you with a proposal for improving the temperature control on your present machine The machine uses a hot-air knife to cleanly remove excess solder from printed circuit boards, this is a great concept, but the hot air temperature control lacks reliability According to Wing, engineers at WSSI have improved the reliability of the critical temperature controls The new system still has the four sensitive integrated circuits controlling the temperature, but the new machine has a backup for each. The four integrated circuits have reliabilities of 0 91,093,095, and 097 The four backup circuits all have a reliability of 0.91 a) The overall reliability of the new temperature controller = 9786% (enter your response as a percentage rounded to two decimal places) b) If you pay a premium, Wing says he can improve all four of the backup units to 0.94 The overall reliability of the new temperature controller with the upgraded backup unit = [% (enter your response as a percentage rounded to two decimal places) The number of yearly breakdowns for the power generator observed over the past 20 years at Orlando Utilities is presented in the following data Number of breakdowns Number of years in which breakdowns occurred For Orlando Utilities, the expected number of breakdowns =(round your response to two decimal places). 0 3 1 1 2 5 3 3 4 4 5 3 6 1
