- The specialization of structural induction for ______ or _______is called mathematical induction.Facebook has created a new algorithm that is built to detect terrorists in the US by looking at relationships within the data. Currently 200,000,000 people use the platform in the US. 0.001% of people in the US are legitimate terrorists. The Facebook algorithm correctly identifies terrorists 93% of the time. The algorithm incorrectly identifies regular citizens as terrorists 0.07% of the time. How many people are a) Terrorists? b) Not Terrorists? c) Terrorists Identified by the Facebook algorithm? d) Terrorists not Identified by the Facebook algorithm? e) Citizens not Identified by the Facebook algorithm? f) Citizens Identified by the Facebook algorithm?A bag of candy contains 33 pieces of 5 different types.

- Suppose there is a machine that has an unlimited supply of eight different kinds of stickers. Each sticker is as likely to appear as another. Given this answer the following combinatorics problems: (i) Suppose you have one of every kind of sticker. How many ways can you split those stickers between three different people where every person has at least one sticker? Do not include yourself. And given that they are not sorted in any particular order. (ii) How many ways can three people each get a pair of stickers, where each pair is different? Given that it does not matter in which order a person receives the stickers in their pair, BUT it does matter which person gets which pair. (HINT: there are more then six possible stickers in this situation)What is the formula used to calculate degrees of freedom for a t-test for dependent groups? Group of answer choices n – 1 n1 + n2 - 1 n1 – 1 + n2 n1 + n2Let P and Q be two conditions of the same type. Check any objects which cannot satisfy P --> Q, or "none of the above" if none of the others are correct. (In other words, check a box if the property in that box is inconsistent with satisfying P --> Q) Group of answer choices objects that falsify P objects that satisfy Q objects that falsify Q objects that satisfy P none of the above Let P and Q be two conditions of the same type. Check any objects which must satisfy P --> Q or "none of the above" if none of the others are correct.

- Please only answer (g) and (h) (in image), I'm providing the answers to the other questions below. (3) In the part (a) of this question, I’m asking you to give a background situationfor the combinatorics (“counting”) problems in the rest of the question. In parts (b) through(h), you’ll give a question based on that situation for which the calculation I’ve given youwould be the correct answer. a) Combinations and Permutation When one has to choose among a set of objects or people, then combination is used to find the number of ways. The order in which they are chosen does not matter here. On the other hand, if one has to find the number of ways of arranging certain objects, then arrangement is used. Here, the order always matters. For example, find the number of ways in which 4 benches can be occupied by 4 students. Here, the first bench is occupied by 4 students, second one with the remaining 3 students, third one with remaining 2 students, and 4th bench with the last student. Thus,…The Infinite Monkey Theorem states that a monkey hitting keys completely at random on a typewriter for an infinite amount of time will, eventually, type any given text. Even the complete works of William Shakespeare. Some quotes are truly amazing. Consider the famous quote by Gen George S. Patton: "WHEN IN DOUBT, ATTACK" That's 21 amazing characters. Suppose a monkey is seated in front of a KEYBOARD WITH 28 CHARACTERS (one for each of the 26 letters in the alphabet, plus the space bar, and a comma). Suppose the monkey types only 21 characters completely at random. If X is the number of different 21 character strings it could have typed, then the chances that it typed the quote is one divided by X. What is X?

Find the formulafor |E(Kn)|, the number of edges of Kn, using two different methods. Hint: degreesand binomial coefficients, for example. (b) Prove by induction that your formula for |E(Kn)| is correct. Write complete sentences,use the correct language and format for induction proof, and do not leave out anydetails.
