Help pls or i will fail

B, 13,600

Step-by-step explanation:

First we need to figure out the whole area

to do that we do

A = L x H

plug in your numbers

A = 200 x 80 and that gives up 16,000

now we need the area of the smaller rectangular

do the same equation just with the different dimensions

A = 60 x 40 and that gives us 2,400

now subtract the 2,400 from the 16,00 to get the total area of the shaded area

13,600

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 %
