Answer the given problem following the format in the attached file. It is known from experience that 30% of people having a particular disease recover naturally. A drug company created a new medication for the disease. Ten people having the disease were randomly chosen to try the medication, and nine recovered. Assume that the drug was ineffective. What is the chance that at least nine of the ten people who received the medication will recover. *Option for distribution: Bernoulli Distribution, Binomial Distribution, Geometric Distribution, Negative Binomial Distribution, Hypergeometric Distribution, Poisson Distribution, or Multinomial Distribution -Random variable:-Distribution (include explanation): -Computation

According to the Disney Times, 37% of all people in NeverNeverLand are digitally illiterate. Suppose you randomly select eleven people off a city street. Make a probability distribution of the number of digitally illiterate people out of the eleven in the sample. Make a histogram showing the probability distribution of the number of digitally illiterate people out of the eleven people in the sample. Find the mean and standard deviation of the probability distribution. Find the probability of out of eleven people, at least 5 are digitally illiterate. Find the probability of out of eleven people, at most 8 are digitally illiterate. Find the probability of out of eleven people, between 6 and 9, inclusive, are digitally illiterate.
