Y= 2x - 4
y= 2x + 4
y= -1/2x -4
y= 1/2x+4

y=1/2x+4

Step-by-step explanation:

1 square down 2 square to the side you put that in a fraction 1/2 which is the gradient and the y-intercept is what passes through y which is 4

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 %
