The gas tank in ms. wades car holds 20gallons. she has 5 gallons of gas remaining in the tank. if she purchases gas fpr $2.90 per gallon, how much will she pay to fill the tank?
think, 10 gallons would

5 gallons would

so,15 gallons would

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 %
