A sample of 3 balls is to be selected at random from an urn containing 20 balls numbered 1 to 20. Six balls are green, 4 balls are white, and 10 balls are black. How many different samples can be selected?
A bag contains three different balls, one red (r), one blue(b), one white(w). TWO balls are drawn from the bag without replacement one after the other (at random without looking) and the colors recorded. This means once the first color is drawn, the first ball is kept out of the bag and only 2 colors remain when the second ball is drawn. List the sample space. [Use lower case letters for the colors, preserve the given order, commas separating pairs, no spaces.]
A shipment of 9 typewriters contains 2 that are defective. Find the probability that a sample of size 3, drawn from the 9, will not contain a defective typewriter. What is the probability that a sample of 3 of the 9 typewriters will not contain a defective typewriter? (Type an integer or a simplified fraction.)
Suppose that it is known that a certain disease occurs in 4% of the population. Suppose also that we have a certain medical test to determine if person has this disease. The test produces a positive reading on 99.4% of those infected with the disease. Suppose that this test gives a positive result in healthy patients 2% of the time. Assume we have 100,000 random individuals that follow the above information perfectly. Determine the number of false positives.

Suppose there are three balls in a box. On one of the balls is the number 1, on another is the number 2, and on the third is the number 3. You select two balls at random and without replacement from the box and note the two numbers observed. The sample space S consists of the three equally likely outcomes {(1, 2), (1, 3), (2, 3)} (disregarding order). Let X be the sum of the two balls selected. What is the mean of X? Select one: a. 2.0 b. 2.33 c. 4.0 d. 4.33
In a class there are 4 students who are 19 years old and obtained 80 pints in the midterm. There are 6 students who are 19 years old and obtained 50 pints in the midterm. There are 6 students who are 20 years old and obtained 80 pints in the midterm. There are n students who are 20 years old and obtained 50 pints in the midterm. There are no other students. We randomly pick a student in the class, let their age be X and their score by Y. If we are given that X, Y are independent random variables, then compute n.
A person, Joe, claims to be able to "smell" an illness based on the odor of a person's clothing. Joe is given 12 shirts, each worn by a different person, some of whom had the illness and some of whom did not. The shirts were given to Joe in random order and he had to decide whether each shirt had been worn by an ill patient or by a healthy patient. joe identified 11 of the 12 shirts correctly. If we assume that Joe was just guessing, he would have probability 1/2 of correctly identifying each shirt. Find the probability that Joe would identify AT LEAST 11 shirts correctly by random guessing
Suppose that you have 10 cards. 3 are blue and 7 are orange. The 3 blue cards are numbered 1,2, and 3. The 7 orange cards are numbered 1, 2, 3, 4, 5, 6, and 7. The cards are well shuffled. You randomly draw one card. • B = card drawn is blue • O = card drawn is odd-numbered How many elements are there in the sample space? [ Select ] ["7", "10", "2", "3"] P(B) = [ Select ] ["0.7", "0.2", "0.5", "0.3"](Give your answer in decimal form.
The items produced on an assembly line are inspected, and each is classified as either conforming (acceptable), downgraded, or rejected. Overall, 70% of the items are conforming, 20% are downgraded, and 10% are rejected. Assume that four items are chosen independently and at random. Let X1, X2, X3 denote the numbers among the 4 that are conforming, downgraded, and rejected, respectively. Question. • What is the distribution of X1, X2, X3? • What is the probability that 3 are conforming and 1 is rejected in a given sample?
