Which expression is equivalent to a^4 ⋅ b^2 ⋅ a^‐4 ⋅ b^4?

Varibles do NOT matter. So, we're going to want to find an answer that has either a change of a varible, or the same answer, of course. Therefore, answer is (the last option).

(b^4)

I hope this helps you!

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 %
