Explain why the sum of a rational number and an irrational number is always irrational.

Irrational numbers are contradictory, even when combined with a rational number.

Step-by-step explanation:

Since the assumption that the sum of a rational and irrational number is rational leads to a contradiction, the sum must be irrational.

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 %
