Sorry to be annoying but there's another question i don't understand... :)

8.20

Step-by-step explanation:

6.15*4=24.6

since they only bought 3 tickets because of the deal

you divide 24.6 by 3 and get 8.20

A ticket costs $8.20.

Step-by-step explanation:

This is because since they only have to buy three tickets, they split the money between each of the four of them. So, we would need to do $6.15 * 4 which equals $24.60, then we divide this number by three to get $8.20 which is the cost of one ticket.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
