Question
mating for each gehe (celhter ies) Problem 4. A computer student keeps a backup copy of the programs, developed on the hard disk or a memory stick. The is a 10% chance that the hard disk will crash but a 50% chance that the memory stick will be lost, what is the probability that the student's work will get lost? Problem 5. Carlton&Devore;, Exercise 5, Section 1.1. (See this textbook in our textbook folder-with VPN).). Three components are connected to form a system as shown in Figure 2. Because the components in the 2-3 subsystem are connected in parallel, that subsystem will function if at least one of the two individual components functions. For the entire system to function, component 1 must function and so must the 2-3 subsystem. Suppose that the probability of each component functioning is 0.85. Compute the probability that the entire system functions.
Explanation / Answer
Problem 4
The student work will be lost if hard disk is crashed and memory stick will be lost
P( Student work will be lost ) = 0.10*0.50 = 0.05
Problem 5
P( system work ) = 0.85*(0.85+0.85-0.85*0.85) = 0.830875
