A certain system can experience three different types of defects. Let Ai (i = 1,2,3) denote the event that the system has a defect of type i. Suppose that

P(A1) = 0.29, P(A2) = 0.27, P(A3) = 0.36,
P(A1 ∪ A2) = 0.52, P(A1 ∪ A3) = 0.57,
P(A2 ∪ A3) = 0.58, P(A1 ∩ A2 ∩ A3) = 0.01
(a) Find the probability that the system has exactly 2 of the 3 types of defects.
(b) Find the probability that the system has a type 1 defect given that it does not have a type 2 or type 3 defect.

Let An = {ai} n i=1 denote a list of n distinct positive integers. The median mA of An is a value in An such that half the elements in An are less than m (and so, the other half are greater than or equal m). In fact, the median element is said to have a middle rank. (a) Develop an algorithm that uses Sorting to return mA given An. (6%) (b) Now assume that one is given another list...

Let XiXi for i=1,2,3,…i=1,2,3,… be a random variable whose probability distribution is Poisson with parameter λ=9λ=9. Assume the Xi are independent. Note that Poisson distributions are discrete. Let Sn=X1+⋯+Xn. To use a Normal distribution to approximate P(550≤S64≤600), we use the area from a lower bound of __ to an upper bound of __ under a Normal curve with center (average) at __ and spread (standard deviation) of __ . The estimated probability is __
