A company offers a raffle whose grand prize is a $35,000 new car. Additional prizes are a $900 television and a $600 computer. Tickets cost $18 each. Ticket income over the cost of the prizes will be donated to charity. Use the method of Example 9.8.5 to answer the following question. If 3,000 tickets are sold, what is the expected gain or loss (in dollars) of each ticket?

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
