Rick Wing, salesperson for Wave Soldering Systems, Inc. (WSSI), has provided you with a proposal for improving thetemperature control on your present machine. The machine uses a hot-air knife to cleanly remove excess solderfrom printed circuit boards; this is a great concept, but the hot-air temperature control lacks reliability. Accordingto Wing, engineers at WSSI have improved the reliability of the critical temperature controls. The new system still hasthe four sensitive integrated circuits controlling the temperature, but the new machine has a backup for each. Thefour integrated circuits have reliabilities of 0.82, 0.84, 0.86, and 0.88.

Please do not give solution in image format thanku You have won two tickets to a Lady Gaga concert in Atlantic City. The concert is three days from now and you have to make travel arrangements. Calculate the reliability of each of the following options: Drive to Washington, DC, and take the bus to Atlantic City from there. Your car has a 79% chance of making it to DC. If it doesn’t make it to DC, you can hitchhike there with a 40% chance of success. The bus from Washington DC to Atlantic City has a 93% reliability.
