Suppose that in a small village about 90% of the residents are of Hawaiian ancestry. Let n=1, 2, 3,… represent the number of people you must meet until you encounter the first person of Hawaiian ancestry in the village. Write the expression for the probability distribution of the random variable n.

In a statistics class there are 18 juniors and 10 seniors; 6 of the seniors are females, and 12 of the juniors are males. If a student is selected at random, find the probability of selecting a senior or a female

A jar contains 12 coins: 6 pennies, 2 nickels and 4 dimes. A child selects 2 coins at random without replacement from the jar. Let X be the sum of the value of the 2 coins. Determine the probability distribution of X. Please enter the values for x in increasing order. Round your answers to three decimal places, if necessary. Hint: If you are picking two different coins, remember that you can pick one first, then the other or the other way around, and you will still end up with the same two coins. X A. P(X = x) 2 0.227 6 10 0.015 11 15 20 .091 If you were to randomly draw two coins from this jar, how many cents do you expect to have on average? (Averages of discrete things CAN be decimals!)

Regifting is defined as the act of taking a gift that has been given to you and presenting it as a gift to someone else. According to survey conducted by a credit card company regarding consumer spending, 81% of the respondents felt that it was socially acceptable to regift during the holiday season (big sigh of relief). Suppose a random sample of 10 holiday shoppers was selected. Complete parts a through d. a. What is the probability that 9 shoppers from this sample felt that regifting was socially acceptable? The probability is. (Type an integer or decimal rounded to four decimal places as needed.) b. What is the probability that more than 7 shoppers from this sample felt that regifting was socially acceptable? The probability is. (Type an integer or decimal rounded to four decimal places as needed.) c. What is the probability that fewer than 10 shoppers from this sample felt that regifting was socially acceptable? The probability is (Type an integer or decimal rounded to four…

50% of the senior class is female. Of the females, 20% are school athletes. What is the probability that a senior selected at random is a female school athlete?

The table shows the breakdown of 96 thousand single parents on active duty in a country's military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the military is in the Air Force or the Marine Corps. Army Navy 24 8 32 Male 23 Female 10 Total 33 The probability that a randomly selected single parent in the military is in the Air Force or the Marine Corps is (Type an integer or decimal rounded to the nearest thousandth as needed.)

In a large population, 16% of the people are left-handed. In a random sample of 5 people, determine the following: (a) the probability that exactly 2 people will be left-handed; (b) the probability that no more than 2 people will be left-handed; (c) the probability that at least 2 people will be left-handed in the sample.

The probability that an adult possesses a credit card is.75. A researcher selects two adults at random. The probability that the first adult possesses a credit card and the second adult does not possess a credit card Type your answer here:

A crate contains 50 led light of which 5 are defective and 45 are not. A Quality Control Inspector randomly samples 12 led light without replacement. Let X be the number of defective led light selected. Find the probability that less than 2 led light are defective. Determine the probability distribution to solve this problem.

Suppose that a box contains 8 cameras and that 4 of them are defective. A sample of 2 cameras is selected at random. Define the random variable Xas the number of defective cameras in the sample. Write the probability distribution for X.Write your answer in fraction form or round to 3 decimal places.
