To be fair, the company decides that the two individuals who get to attend will have their names drawn from a hat. Determine the sample space of the experiment. That is, list all possible simple random samples of size n=2. (a) How many events are in the sample space? [x] For parts b and c: Write your answer as a fraction in simplifed form. Use the “/” for your fraction bar. For example, one-half would be written as 1/2. (b) What is the probability that John and Dominique attend the conference? [y] (c) What is the probability that John stays homestays home? Write your answer as a fraction in simplifed form. [z]

(Continued from previous question) A recent census found that 51.8% of adults are female, 10.1% are divorced, and 6.1% are divorced females. For an adult selected at random, let F be the event that the person is female, and D be the event that the person is divorced. Determine P(F or D), and interpret your answer in terms of percentages. The percentage you found for P(F or D) represents [x]

Write your three body paragraphs and conclusion paragraph here. Use your outline as a guideline. Just add extra spaces to separate each paragraph. Each body paragraph needs to be at least 5 sentences, and your conclusion needs to be at least three sentences (make sure you restate your thesis in your conclusion paragraph as well). Also, don’t forget transitions (first, next, finally….ect.) since this is a process essay which is telling someone how to do a process.
