Suppose 2n people come to the game and every individual pays for their own "ticket" and that by the end of the evening there were exactly n with 50 Dhs notes and exactly n with 100 Dhs notes. We want to think about different the implications of them arriving in different orders. For example, if all the people with 100s arrived first then we would need to issue 50 IOUs(I Own You). Draw a flow chart and answer by logic and math.

The next two questions refer to the following belief network with random variablesF0,F1,…,F4 which only take the values 0 and 1. Which of the following statements are true about this belief network (1), (3) and (4) only :(1) F0 and F3 are independent given F1,F2 ;(2) F0 and F2 are independent;(3) P(F0∣F1,F2)=P(F0∣F1,F2,F3,F4) ;(4) F0 and F4 are independent. In general, to define the joint probability distribution P(F0,…,F4) one requires up to 25−1 entries in the table of probabilities. For the belief network above, one can compute the joint probability distribution P(F0,…,F4) using the following number of conditional probabilities
"Equatable and Comparable" in the Swift Programming: The Big Nerd Ranch Guide (2nd Ed.) e-book: Point’s current conformance to Comparable yields some confusing results. let c = Point(x: 3, y: 4) let d = Point(x: 2, y: 5) let cGreaterThanD = (c > d) // false let cLessThanD = (c < d) // false let cEqualToD = (c == d) // false As the above example demonstrates, the trouble arises in comparing two points when one point’s x and y properties are not both larger than the other point’s. In actuality, it is not reasonable to compare two points in this manner. Fix this problem by changing Point’s conformance to Comparable. Calculate each point’s Euclidean distance from the origin instead of comparing x and y values. This implementation should return true for a < b when a is closer to the origin than b. Use the formula shown in below Figure 25.1 to calculate a point’s Euclidean distance. Figure 25.1 Euclidean distance Euclidean distance
