The sum of two consecutive integers is 131

65 and 66

Step-by-step explanation:

x + (x+1) = 131

2x + 1 = 131

2x = 131 - 1 = 130

x = 65

x + 1 = 66

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 %  

step-by-step explanation:

only 10/60 isn't equivalent

hope this : )
