You go to school in a college town. you know that there are 2000 students enrolled in the school, but you don’t know the population of the town (without students). you walk up and down the main streets of the town, stop people, and ask them if they are students or not. you ask 100 people, and 60 of them say they are students. estimate the nonstudent population of the town.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

( give brainliest)

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 %
