Conjecture proof

Step-by-step explanation:

 In the field of mathematics, conjectures means arriving at a conclusion without complete or proper information, for which the proof or disproof have to be found yet. It is a statement in mathematics that has not been proved rigorously.  Conjectures come into picture when someone notices a definite pattern which can hold true for some cases but that does not confirm that these patterns also hold true for all the other cases. Thus Conjecture proof is not fully accepted.

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 %
