I got this wrong as well. Can someone explain to me this?

-1.5 and 1.5

I don't have those sings but -1.5 goes on the first box and 1.5 goes on the second one

answer: you have to send a photo of the question

step-by-step explanation:

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 %
