:/ - a 20-foot ladder is set up against a building so that the ladder makes an angle of 73° with the ground.
the height, h, is the vertical distance from the top of the ladder to the base of the building. the base, b, is the horizontal distance from the bottom of the ladder to the base of the building. what is the approximate height-to-base ratio?
a. 0.96 : 1
b. 0.31 : 1
c. 3.42 : 1
d. 3.27 : 1

since height to base ratio is tan73 so approx ratio is 3.27

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 %

ask the math teacher she or he would know lol.
