1)A system composed of n separate components is said to be a parallel system if it functionswhen at least one of the components functions. For such a system, if component i,independent of other components, functions with probability p i n i, =1,2,…, what is theprobability that the system functions?2)A student has to sit for an examination consisting of 3 questions selected randomly from alist of 100 questions. To pass, the student needs to answer correctly all the three questions.What is the probability that the student will pass the examination if he remembers correctlyanswers to 90 questions on the list?
