In the diagram below DE is parallel to XY what is the value Y

Those are consecutive interior angles of a transversal across parallel lines.  That mouthful means they're supplementary, adding to 180°.

B. 75

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 %  

step-by-step explanation:

is should be y = 5x
