An engineering system consisting of n components is said to be a k-out-of-n system k ≤ n if the system functions if and only if at least k of its components function. suppose that all components function independently of one another. (a) if the ith component functions with probability pi , 1 ≤ i ≤ 4, compute the probability that a 2-out-of-4 system functions. (b) repeat for a 3-out-of-5 system. (c) repeat for a k-out-of-n system when p1 = p2 = · · · = pn.
