Step-by-step explanation:

If we translate the problem to numbers you will see something like this:

Where:

So you have to solve the equation:

Its a first grade equation, you have to past the value with his product inverse, so the product transform into a division.

Then you have to solve the division between 108 and 9 to obtain the value:

And thats all.

To verify, now you can replace the x on the equation for the obtained value.

Greetings

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 %
