- The joint probability distribution is a probability distribution that defines the simultaneous behavior of at least one random variable. True FalseDrawing upon your considerable experience as a human being, provide an example of a DISCRETE variable which would have a NON-SYMMETRIC probability distribution. Then give an example of some CONTINUOUS variable which would have a NON-SYMMETRIC probability distribution. In each case, INCLUDE A GRAPHICAL DEPICTION OF THE SHAPE OF THE PROBABILITY PATTERN (clearly label your axes), WITH SOME EXPLANATION/JUSTIFICATION OF YOUR BELIEF IN THAT SHAPE.Aircraft arrive at a certain airport at a rate of 2 per hour.

If X denotes the number of white balls drawn and Y denotes the number of red balls drawn, find the joint probability distribution of (X, Y ).A washing machine in a laundromat breaks down an average of three times per month. Using the Poisson probability distribution formula, find the probability that during the next month this machine will have (a) exactly two breakdowns (b) at most one breakdownDiscuss the properties of discrete and continuous probability distributions and give examples of each
- The scenario: Suppose you walk to a bus stop to catch a bus; busses of the line you take to arrive there every 15minutes. You don’t look at your watch and arrive at the bus stop totally at random. For simplicity, we assume that all arriving times (you/the busses) are rounded down to whole minutes. When you and the bus arrive simultaneously, you will be able to catch it. The question: Describe the probability space that models the above-described waiting time experiment, i.e. sample space and the related probabilities.Three friends are tossing separate dices one time. What is the probability of getting three l's? Assume that the dices are perfectly symmetrical and, hence, that each outcome has a probability of -For 10 percent of the products in a category, a firm fails to satisfy all demand during themonth.
