The college student senate is sponsoring a spring break Caribbean cruise raffle.  The proceeds are to be donated to the Samaratian Center for the Homeless.  A local travel agency donates the cruise, valued at $2000.  The students sold 2833 raffle tickets at $5 per ticket.   A. Kevin bought 5 tickets. What is the probability that Kevin will win the spring break cruise to the Caribbean?  ( Round your answer to five decimal places)   What is the probability that Kevin will not win the cruise?  ( Round your answer to five decimal places)   B.  Expected earnings can be found by multiplying the value of the cruise by the probability that Kevin will win.  What are Kevin's expected earnings?  ( Round your answers to two decimal places) Is this more or less than the amount Kevin paid for the five tickets? How much did Kevin effectively contribute to the Samaritan Center for the Homeless?  (Round your answer to two decimal places)

Chuck works at the BuyMore where people can bring in broken computers. When a customer enters the store there is a good chance he will not be paid anything from helping them. But sometimes there is a chance he will be paid to work on their computer. The probability of each amount from a random customer is given in the following table: Job payment $13 $90 $300 $1,400 Probaiblity 0.39 0.1 0.06 0.01 When the next person walks into the BuyMore, how much money can Chuck expect to get from them on average?Answer to two decimals  What is the probability he will get less than $160 from a random customer?Answer to four decimals What is the standard deviation for the payments from the customers?Answer to two decimals  What is the median job payment amount?Answer to two decimals
