) Approximately 5 out of 8 students at Tina's school are on a sports team. Two students design accurate simulations to determine how many
students would need to be randomly selected before 9 students who are
on a sports team are found.
A student places 60 blue marbles in a bag to represent students who are
on a sports team and places some yellow marbles in the same bag to
represent students who are not on a sports team. The student will
randomly select a marble, record the color, and return the marble back to
the bag. How many yellow marbles does the student place in the bag?
