Which points are solutions to the system of inequalities shown below? check all that apply.

y < x + 1
y < 4
x < 6
a.(1, 3)
b.(1, -1)
c.(5, 9)
d.(4, -2)
e.(5, 5)
f.(4, 2)

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 %
