a) The overall reliability of the new temperature controller =____% (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 0.88. The overall reliability of the new temperature controller with the upgraded backup unit =_____% (enter your

response as a percentage rounded to two decimal places).

to cleanly remove excess toldee from printed circuit boards: this is a great concept, but the hof air temperature control lacks reliability. Acoording to Wing, engineers at Ws5s have improved the reliablity of the cricicak temperature controls. The new oystem stil has the four sensilive integrated circuits controling the temperature, but the now machine has a beckup for bach. The four integrated circuls have retsbeltes of 0.87,0.89,0.91, and 0.93. The four backip crrauts all have a reliablity of 0.87, a) The cveral reliabicty of the new lemperature controler = N (enter your response as a percentage rounded to hwo decimal places)
