9. Consider the sample space Ω {1.2.3.4 } (the set of all natural numbers). We want to show that there is no probability measure on 2 under which "all outcomes are equally likely" Let's argue by contradiction. Suppose P is a probability measure such that P)) has the same value for all n e2. Let's see what can go wrong. (a) Suppose P)> 0. Which axiom of probability will be violated? (b) Suppose P((n)) = 0, which axiom of probability...
3. Consider the following experiment. We have an urn with two marbles numbered 1 and 2 We pick a marble randomly, write down its number and return it to the urn. Then we add a marble with the mumber 3 to the um, choose one of the three marbles randomly, record its number and return it to them. We repeat this over and over: before thek + 1)st pick we add a marble with with the number k + 2...
2).
a.b.
A probability experiment is conducted in which the sample space of the experiment is S = {3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}, event F= {7, 8, 9, 10, 11, 12}, and event G = {11, 12, 13, 14). Assume that each outcome is equally likely. List the outcomes in F or G. Find P(F or G) by counting the number of outcomes in F or G. Determine P(F or G) using the...
4. Suppose an experiment consists of picking a student from the set of all students registered on the UCSD campus this quarter. It is not necessary to assume that all students are equally likely to be picked, but you may make this assumption if it makes you feel happier and more confident. (a) Consider the two events: Athe student has had four years of high school science (FYS, the student has had calculus in high school If the probability that...

4. Consider a inap φ : I 1,11 > 10, 1] defined by φ(z) :-12. Let X and Y be random variables related by the map φ, i.c., Y-o(X) (their sample spaces are then given by SX-1 1,11 and SY-10,1]). Let FY be the σ-algebra and Hy the probability measure you worked out in problem 3. Compute the adaptod ơ algebra X and the corresponding probability measure x (i.e., use the formula X (ф ія, )-, Y (S.) for any...
Law of Large Numbers We saw in the Theoretical and Experimental Probability Lab that as we do more and more repetitions or trials of an experiment, the closer the experimental probability gets to the theoretical probability. This is called the Law of Large Numbers. Why is the Law of Large Numbers important? Why do we do experiments and find experimental probability when we could just use theoretical probability? Inferential statistics makes inferences about populations using data drawn from the population....
