1. Shrek wants to buy a birthday gift for Fiona. Assume that the amount of time spent deciding what to get forher takes X days, where the distribution of the continuous random variable X has the memoryless propertyand its range is [0, 00). The probability that he takes more than 3 days to decide what to buy is e-6z 0.0025.When he has decided to get a certain gift, then the amount of time taken to procure it takes an additionalex days. What is the expected amount of days it takes Shrek to get Fiona's gift (including both the decisionmaking time and the time required for procuring it)?

Given that the amount of time spent deciding what to get for her takes X days, where the…

An event is biased such that an outcome "x" is thrice as likely to occur as "y". Find the expected value of "y" outcomes if the event happened twice given that "x" and "y" are discrete random variables with a unit value of 1 and both of them are the only possible outcomes of the said event.

According to a study by Weight Loss R US of their live-in weight loss program, the people who follow his program lose between 6 and 14 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month. Suppose it is known that the individual lost more than ten pounds in a month. Find the probability that he lost less than 10 pounds in the month. (round your answers to 4 decimals.)
