Please submit the four asterisked problems below in class on Wednesday, April 17 Be sure your work is labeled when appropriate. For example, if your solution involves "P(A)," make sure it is clear what event A is and which number in your calculation is P(A); if your solution involves a random variable X make sure it is clear what X is. 1. * An urn contains 999 red balls and 1 green ball. 2000...
Homework: Assignment 11 Score: 0 of 1 pt 8.5.4 1 of 25 (17 complete) Score: 61.67%, Ques For the experiment described below, let x determine a random variable, and use your knowledge of probability to prepare a probability distribution. Three balls are drawn (with replacement) from a bag that contains 5 orange balls and 3 green balls. The number of green balls is counted. A probability distribution for the given experiment is as follows. (Round to four decimal places as...
Michael has a box of colored balls. It contains two red balls, two green balls, two yellow balls, and five blue balls. Michael draws a ball at random from the box Let R denote the event that the ball he draws is red, and let B denote the event that the ball he draws is blue. What is Pr(R|B)? What is Pr(R|B′)? Enter your answers as whole numbers or fractions in lowest terms. A bag contains four 1-dollar bills, three...

Be sure to carefully follow the instructions about entering your answer. In most open-answer problems, only a number is required (i.e., no units, no percentage sign, etc...). Pay close attention to the number of decimal places requested. You should use a TI-84 PLUS calculator for all procedures where appropriate.
