One five and dime (II). Someone simultaneously flips a penny, a nickel, and a dime. Make a list of all the possible outcomes. What is the proba bility of seeing three presidents? What is the probability of seeing exactly two presidents? Suppose now that you do not see the outcome, but you are told that a president is showing. Now, what is the probability of seeing three presidents? Suppose, instead, that you are told that Lincoln is showing. What now is the probability of seeing three presidents? Why do the answers differ?

- 2. Consider the following argument: (a) Seabiscuit is a thoroughbred. Seabiscuit is very fast. Every very fast racehorse can win the race. .. Therefore, some thoroughbred racehorse can win the race. Let us define the following predicates, whose domain is racehorses: T(x) x is a thoroughbred F(x) x is very fast R(x) x can win the race : Write the above argument in logical symbols using these predicates. (b) Prove the argument using the rules of inference. Do not make use of conditional proof. (c) Rewrite the proof using full sentences, avoiding logical symbols. It does not need to mention the names of rules of inference, but a fellow CSE 16 student should be able to understand the logical reasoning.arrow_forwardFind the inverse of the matrix, or determine that the inverse does not exist for: € (b) 7 -12 240 1 1 1 (c) 2 3 2 2 17 036 205 20 (d) -1 1 2 1 T NO 1 0 -1 00 1 0 02 (e) 1 0 00 0 0 1 1arrow_forward4. Prove the following. Use full sentences. Equations in the middle of sentences are fine, but do not use logical symbols. (a) (b) (n+3)2 is odd for every even integer n. It is not the case that whenever n is an integer such that 9 | n² then 9 | n.arrow_forward

When a margin of error is reported for a survey, it includes a. random sampling error and other practical difficulties like undercoverage and non-response b. random sampling error, but not other practical difficulties like undercoverage and nonresponse c. practical difficulties like undercoverage and nonresponse, but not random smapling error d. none of the above is corretarrow_forward
