For the following straight lines on a graph, determine the area of the triangle in square units, enclosed by the X-axis, the Y-axis and the given Line. 1. x + y = 9
2. x-y=1
3. y=3+x
4. y = 4x+2
5. x = 3y-5

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 %
