Let N be the set of natural numbers², and consider the random experiment of choosing a natural number randomly, so that all numbers are equally likely. Determine the sample space, the event space, and the probability function of this experiment. Then, write down a mathematical expression for identifying the event A which occurs when the selected number is divisible by 3, and calculate P (A). Do the three axioms of probability hold? If yes, prove your claim, and if no, employ a reasonable slight change to make the three axioms satisfied. Thinking about this statement might help: Since there are infinitely many natural numbers, the chance of any single number is zero. Thus, it holds for example that P (B) = 0, where B = {3,5, 6, 2020, 2021}.

Fuego Ironworks has an inspection system for the batches of Chroma purchased from vendors. A batch typically consists of 15 Chromas. In the inspection system, a random sample of 5 is selected and tested. If there are 2 defective Chromas in the batch of 15, what is the probability that: a. there will be 1 defective chroma b. both defective chroma are detected
A man wants to adopt a puppy from an animal shelter. At the shelter, he finds eight puppies that he likes, a male and female puppy from each of the four breeds of water spaniel, chow chow, collie, and Labrador. The puppies are each so cute that he cannot make up his mind, so he decides to pick the dog randomly. Find the probability that the man chooses a male puppy. E The probability of choosing a male puppy is. (Type a simplified fraction.)
A card is selected at random from a standard deck of playing cards. Determine the number of elements in the sample space for selecting a card at random from a standard deck of playing cards. n(S) = Let E be the event that the card selected is a face card (jack, queen, or king). Determine the number of elements in event E. n(E) = Find the probability of event E. (Enter your probability as a fraction.)
ESP Experiment. A person has agreed to participate in an extrasensory perception (ESP) experiment. He is asked to randomly pick two numbers between 1 and 6. The second number must be different from the first. Let H= event the first number picked is a 3, and K= event the second number picked exceeds 4. Determine a. P(H). b. P(K| H). c. P(H&K). Find the probability that both numbers picked are d. less than 3. e. greater than 3.
Flip two fair coins. Then the sample space is {HH, HT, TH, TT} where T = tails and H = heads. The outcomes HT and TH are different and the HT means that the first coin showed heads and the second coin showed tails. The TH means that the first coin showed tails and the second coin showed heads. Let A = the event of getting at least one tail while letting B = the event of getting all tails. What is the probability of event A ∩ B? a. 0.66 b. 0.50 c. 0.25 d. 0.75
Use the following results from a test for marijuana use, which is provided by a certain drug testing company. Among 141 subjects with positive test results, there are 28 false positive results; among 155 negative results, there are 5 false negative results.

A coin is tossed three times. An outcome is represented by a string of the sort HTT (meaning a head on the first toss, followed by two tails). The 8 outcomes are listed in the table below. Note that each outcome has the same probability. For each of the three events in the table, check the outcome(s) that are contained in the event. Then, in the last column, enter the probability of the event.
