Hlp pls! i need this done very soon

The scale factor is 0.5

It is a reduction

Step-by-step explanation:

∵ The length of the side of the first Δ = 3.4

∵ The length of the side of the second Δ = 1.7

∵ 1.7/3.4 = 1/2 = 0.5

∴ The scale factor is 0.5

∵ The second Δ is smaller than the first Δ

∴ It is a reduction

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 %
