First question: Let X be a discrete random variable. If Pr(X<6) = 1/5, and Pr(X>6) = 1/7, then what is Pr(X=6)? Please specify your answer in decimal terms and round your answer to the nearest hundredth (e.g., enter 12 percent as 0.12). **** Second question: Let X be a discrete random variable. If Pr(X<8) = 1/5, and Pr(X<=8) = 3/10, then what is Pr(X=8)? Please specify your answer in decimal terms and round your answer to the nearest hundredth (e.g., enter 12 percent as 0.12).

Cool Beans is a locally owned coffee shop that competes with two large coffee chains, PlanetEuro and Frothies. Alicia, the owner, is considering two different marketing promotions and thinks that a CLV analysis will help her decide the best course of action. An average specialty coffee drink sells for $4.34 and has a margin of 81%. One promotion is providing loyalty cards to her regular customers that would give them one free specialty coffee drink after 10 regular purchases. Alicia estimates that this will increase the frequency of their purchases by 8%. Currently, her customers average buying 2 specialty drinks per week.
