particular disease is tested for and the results determined that it occurs in abut 1 of every 800 black females and about 1 of every 185,000 non-black females. Find the empirical probability that a randomly selected black female will have the disease. The probability is _________. (Type an interger or decimal rounded to three decimal places as needed.)

From the U.S. Census Bureau and the article “U.S. Prison Population Falls for Third Year” by B. Montopoli of CBS News, we found that about 1 in every 200 Americans are in prison. Suppose 500 Americans are randomly sampled. Let X represents the number of Americans currently in prison. n = λ = (Round to two decimal places) Calculate the probability that three of the 500 Americans are currently in prison. Round your answer to four decimal places, e.g., 0.XXXX or .XXXX. P(X = 3) = Calculate the probability that at least three of the 500 Americans are currently in prison. Round your answer to four decimal places, e.g., 0.XXXX or .XXXX. P (X ≥ 3) = 1 – P (X < 3) = Calculate E(X) = µ. Round your answer to two decimal places, e.g., 0.XX or .XX. µ = E(X) = Calculate the standard deviation of X. Round your answer to two decimal places, e.g., 0.XX or .XX. σ =
The reported rate for colorblindness for men ages 65 and older is 12%. Assume this estimate is the true population proportion of men ages 65 and older. A SRS of 25 men ages 65 and older is taken. Calculate the probability that proportion of men ages 65 and older who have colorblindness is more than 0.10. A. 3783 B. 6217 C. This can’t be done because np is not greater than D. This can’t be done because n is not greater than 30 and we are not told that the variable is normally distributed.

Let's calculate the probability of finding someone special. Using a form of Fermi's Paradox (the difference between having limited or no choices to having high amount of choices). Let's calculate your probability using the following data. Multiply the number and all percentages together N (subscript p): Number of people = your target population (number of people in your state). Broward County, FL is 1,953, 251 million. Dade County, FL is 2,717,251 million. Palm Beach County, FL is 1, 497,251 million. Harris County, TX is 4,731,251 million. (example: 1,374,251 x .5 x .44 x .37 x .25 x.10 x.10 = 279 people are potential special people for you) times f (subscript g) = target gender (multiply as a decimal. Example: 0.5 for either sex or 1.0 for both sexes) times f (subscripts) = single people (multiply as a decimal) About 44% of people are single at any given time. f (subscript e) = the number of people you'll run into (multiply as a decimal).
