Mrs. Delgado said that 21 out of 25 students passed the test. What percent did NOT pass the test?

16% of the students did not pass the test.

Step-by-step explanation:

Since 25 is 1/4 of 100, multiply it by 4 to equal 100.

Now multiply the percentage passed by 4. This equals 84.

84 out of 100 = 84%

So, the rest of the students(the ones who did not pass) is 16% of the class.

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 %
