Twelve of the 20 students in ms. sarno’s homeroom are female. each month, ms. sarno randomly selects a student to act as “teacher’s .”

which simulation best models the selection of female “teacher’s ” for january, february, march, and april?

a spinner, divided into 5 congruent sectors with three of the sectors representing female students, is spun 12 times.

a coin, with heads up representing female students, is flipped 4 times.

a bag of 15 marbles, with 9 marbles representing female students, has a marble drawn 4 times with replacement.

a number cube, with odd numbers representing female students, is rolled 12 times.

Number of students in Ms. Sarno's  homeroom = 20

Number of female  in Ms. Sarno's  homeroom = 12

Number of Male  in Ms. Sarno's  homeroom = 20 - 12 = 8

Probability (Selecting Female act as “teacher’s helper.” )=

Probability (Selecting male act as “teacher’s helper.” )=

Out of Four options given , the best simulation describing above Situation is ,

Option (C) A bag of 15 marbles, with 9 marbles representing female students, has a marble drawn 4 times with replacement is best simulation describing above situation.

The reason being, if 9 marbles represent female students out of 15 marbles and we have to select 4 females for four months that is for January, February, March, and April.So, marbles are drawn 4 times with replacement .

Probability of choosing four female as teacher's helper for four months if a  bag of 15 marbles, with 9 marbles representing female students, has a marble drawn 4 times with replacement.  =
