Hi, math is not my strong suit, can someone please answer this equation correctly, and quickly? I also have two more for you to answer, thank you, and have a good day! 12x+5y, where x = ½, y = 6, and z = 3.

3z

1,645,493,059.35

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 %
