### Probability Experiment: Rolling Two Fair Dice#### Experiment DescriptionConsider the experiment:\[ E = \text{Two fair dice are cast and the sum of the spots shown on the uppermost faces are recorded, with sample space} \]The sample space for this experiment is:\[ \Omega = \{2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12\} \]#### ObjectiveProve directly that the elementary events (singleton subsets) are _not_ equally likely by repeating \( E \) a large number of times and computing the relative frequencies of the singleton subsets of \( \Omega \).

Question #1 Part A & Part B.
Correct answer will be upvoted else downvoted. Code and output screenshot. Anticipating calculations utilized in VK have effectively assessed the likelihood for every occasion to occur. Occasion in line I and section j will occur with likelihood ai,j⋅10−4. Every one of the occasions are autonomous together. How about we call the table winning if there exists a line to such an extent that all n occasions on it occur. The line could be any flat line (cells (i,1),(i,2),… ,(i,n) for some I), any upward line (cells (1,j),(2,j),… ,(n,j) for some j), the fundamental corner to corner (cells (1,1),(2,2),… ,(n,n)), or the antidiagonal (cells (1,n),(2,n−1),… ,(n,1)). View the likelihood of your table to be winning, and output it modulo 31607 (see Output area). Input The primary line contains a solitary integer n (2≤n≤21) — the elements of the table. The I-th of the following n lines contains n integers ai,1,ai,2,… ,ai,n (0<ai,j<104). The likelihood of occasion in cell…
Generate a probability histogram of the number of rolls required of two dice before a sum of “7” appears (graphical answer followed by Matlab code). Note: Don’t plot experiment that took more than 60 rolls.
Appendix A 10-Fold Cross Validation for Parameter Selection Cross Validation is the standard method for evaluation in empirical machine learning. It can also be used for parameter selection if we make sure to use the training set only. To select parameter A of algorithm A(X) over an enumerated range d E [A1,..., A] using dataset D, we do the following: 1. Split the data D into 10 disjoint folds. 2. For each value of A e (A1,..., Ar]: (a) For i = 1 to 10 Train A(A) on all folds but ith fold Test on ith fold and record the error on fold i (b) Compute the average performance of A on the 10 folds. 3. Pick the value of A with the best average performance Now, in the above, D only includes the training data and the parameter A is chosen without the knowledge of the test data. We then re-train on the entire train set D using the chosen A and evaluate the result on the test set.

solve with matlab.suppose that two fair dice are tossed repeatedly and the sum of the two uppermost faces is determined on each toss. what is the probability that we obtain a sum of 3 before we obtain a sum of 7? Please just write matlab code that solves this problem using simulation
Considering the problem of performing rapid COVID test among a large group of people. Assuming there are exactly 1 positive case among N people, and you are asked to find the positive case with the least number tests. 1. A straight forward approach is to test every single person, which requires N tests in total. Can you design a testing framework that works better than the greedy one under, even under the worst-case scenario? Write the pseudo code for your approach and briefly explain the time complexity of your approach. 2. Based on your framework, if there are 1,000 people, what are the maximum number of tests that need to be performed in order to identify the positive case (number of tests required in the worst case)?
