Since there are limited stocksavailable, she decided to start another business by making a face mask. She startedselling face masks from day 1 to day 10. The data she collected is shown in the tablebelow.Illustrate a probability distribution of a random variable X showing the number offace mask sold per day and its corresponding probabilities.来十DayNumber of Face Mask (X)12522031541451510128109.151014

A article recently reported that 65% of American adults said they would get the COVID vaccine if they were given the opportunity. Imagine I took a random sample of 700 American adults and found 68% of my sample said they would get the COVID vaccine if they were given the opportunity. What is the chance I would get results like this if the true proportion were 65%? Use the sampling distribution of the proportion to find the probability that I would get 68% or more from my sample willing to take the vaccine given a true proportion of 65%. Show your work on paper including what you are entering into technology and put your answer in a complete sentence.
Dr. Verde conducted an experiment in which she randomly assigned each subject a colored pencil and then asked them to choose their favorite color. Her results showed that neither the distribution of the assigned pencil colors or the subjects' preferred colors conformed to their expected theoretical probability values. If she repeats the experiment with a much larger sample, how would you expect her results to change and why? Answer in complete sentences. UPLOAD
A small river is found to be polluted due to the chemical waste from two major industries, A and B. Due to the strict standards enforced by the EPA, the probability of controlling the pollutions from A and B are 0.7 and 0.85, respectively, in the next two years. It is estimated that, if only one of the industries complies with the strict standards of EPA, there is a 75 percent probability of controlling the pollution in the river to an acceptable level. (a) Find the probability of controlling the pollution in the river in the next two years. (b) If the pollution in the river is not controlled in the next two years, what is the probability that it is caused entirely by industry A?
