Identificar qué propiedad del conjunto de los números naturales se aplica en cada ejercicio? a. 86 + 0 = 86
b. 13 × (10 - 4) = 13 × 10 – 13 × 4
c. 11 × 6 = 6 × 11
d. 7 + (9 + 5) = (7 + 9) + 5
e. 1 x 153= 153 x 1
f. 20 + 16 = 36
​

the answer is 28

step-by-step explanation:

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 %
