Jeriel recorded the grade-level and instrument of everyone in the middle school School of Rock below.

Based on these results, express the probability that a seventh grader chosen at
random will play the drums as a fraction in simplest form

9/43

Step-by-step explanation:

Add up the amount of people playing instruments total and put that number under the amount of people playing drums. ez pz

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 %  

step-by-step explanation:

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
