There are 143 students on the school's Math Olympiad team in a 5:6 boy to girl ratio.

How many girls are on the
team?

78 girls

Step-by-step explanation:

5:6

5+6=11

143/11=13

6*13=78

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 %
