ILL GIVE YOU BRAINLIEST

2 since it’s positive

4x^2+9x-7

a=4 b=9 c=-7

B^2-4ac

= (9)^2- 4 (4)(-7)

=193

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 %
