Suppose that a sample space has five outcomes {O1, O2, O3, O4, O5} with corresponding weights
w1 = 1/11, w2 = 2/11, w3 = 3/11, and w4 = 2/11. Answer the following questions:
(a) What is the value of w5?
(b) What is Pr[{O3, O4}]?
(c) What is Pr[{O1, O2, O3} ∪ {O2, O3, O4}]?

Definition Definition For any random event or experiment, the set that is formed with all the possible outcomes is called a sample space. When any random event takes place that has multiple outcomes, the possible outcomes are grouped together in a set. The sample space can be anything, from a set of vectors to real numbers.

Assume that a tennis coach from Texas wants to develop a rally test that can classify players’ performance level accurately. The coach randomly selected 20 tennis players, 10 players are Super Champs (high level), another 10 are Challengers (low level). The coach feeds 10 balls to each of players and sets up the cutoff score of 8. Namely, if a player who can return 8 out of 10 balls to a specific area, is considered a high level. Otherwise, they are considered as low level performance. The table below showed the numbers that players can return balls to the specific area. What is the contingence coefficient?

A QR code photographed in poor lighting, so that it can be difficult to distinguish black and white pixels. The gray color (X) in each pixel is therefore coded on a scale from 0 (white) to 100 (black). The true pixel value (without shadow) the code is Y = 0 for white, and Y = 1 for black. We treat X and Y as random variables. For the highlighted pixel in the figure is the gray color X = 20 and the true pixel value is white, i.e. Y = 0. We assume that QR codes are designed so that, on average, there are as many white as black pixels, which means that pY (0) = pY (1) = 1/2. In this situation, X is continuously distributed (0 ≤ X ≤ 100) and Y is discretely distributed, but we can still think about the simultaneous distribution of X and Y. We start by defining the conditional density of X, given the value of Y : fX|Y(x|0) = "Pixel is really white" fX|Y(x|1) =" Pixel is really balck " Use Bayes formula as given in the picture and find the probability for x = 20 like in the picture.
An analysis of personal loans at a local bank revealed the following facts: 10% of all personal loans are in default (D), 90% of all personal loans are not in default (D'), 20% of those in default are homeowners (H | D), and 70% of those not in default are homeowners (H | D'). If a personal loan is selected at random, P (D | H) = ___. O 0.78 0.02 0.03 0.18 O 0.63
The state runs a lottery once every week in which six numbers are randomly selected from 17 without replacement. A player chooses six numbers before the state’s sample is selected. The player wins if all 6 numbers match. What is the probability that exactly 3 of the 6 numbers chosen by a player appear in the state’s sample? Report answer to 3 decimal places.
3. An integer is randomly chosen from the set 1, 2,..., 100. If this integer is divisible by 2 we let Y = 0, and if it is not divisible by 2 but is divisible by 3 then Y = 1. We let Y = 2 in all other cases. Find mean and variance of Y.

An investigator analyzed the leading digits from 794 checks issued by seven suspect companies. The frequencies were found to be 218, 130, 106, 83, 65, 48, 48, 37, and 59, and those digits correspond to the leading digits of 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively. If the observed frequencies are substantially different from the frequencies expected with Benford's law shown below, the check amounts appear to result from fraud. Use a 0.025 significance level to test for goodness-of-fit with Benford's law. Does it appear that the checks are the result of fraud?
