2. A device consists of two redundant subunits; only one needs to be working for the device to function. The first subunit has two parts Wi and W2, and the second has two parts Ws and W4. In each subunit, both parts must function for the subunit to work. The four parts are independent, identical and equally reliable, with probability p 0.9 of functioning. (a) What is the overall probability the device functions correctly? (b) Suppose you have available two...
please, I need clear writing if you choose to do it by hand. thanks, 2. A device consists of two redundant subunits; only one needs to be working for the device to function.
