David is running a 500 m sprint. so far he has run 300 m. what fraction of the spirit does he have left? ?
__
?
what percent?%

200/500=2/5

40%

Step-by-step explanation:

If the total distance of the sprint is 500m and he's already run 300m, so subtract 500-300 which equals 200.

Then put it in fraction form 500 being the total distance needing to be traveled in all will be your denominator and 200 being the distance left to be traveled will be your numerator. 200/500

Then simplify=200/500 divided by 100/100 equals 2/5.

Then to get it to a percentage divide 2 by 5 which equals  .40

Then convert to a percentage 40%

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 %
