Question

the students at southern junior high school are divided into four homerooms. benjamin just moved into the school district and will be randomly assigned to one homeroom. which methods can be used to simulate this situation? select three options. flip a coin 4 times, once for each homeroom, with heads up representing being assigned to the homeroom represented by that flip. draw a marble from a bag containing 5 white marbles, 5 black marbles, 5 red marbles, and 5 green marbles, with each color representing a different homeroom. use a random number generator with 1, 2, and 12 representing the first homeroom, 7, 9, and 10 representing the second homeroom, 3, 8, and 11 representing the third homeroom, and 4, 5, and 6 representing the fourth homeroom. roll a number cube with 1 representing the first homeroom, 2 representing the second homeroom, 3 representing the third homeroom, and any other outcome representing the fourth homeroom. spin a spinner with 8 congruent sections with 2 sections assigned to each homeroom.

Explanation:

1. Drawing a marble from a bag with 4 - color - coded sets of marbles (white, black, red, green) gives 4 equally - likely outcomes, similar to 4 homerooms.
2. Using a random number generator with 12 numbers divided into 4 groups of 3 numbers each creates 4 equally - likely groups representing the 4 homerooms.
3. Spinning a spinner with 8 congruent sections where 2 sections are assigned to each homeroom also gives 4 equally - likely outcomes for the 4 homerooms.

• Flipping a coin 4 times is incorrect as a coin has 2 outcomes per flip and multiple flips don't directly simulate 4 equally - likely single - event outcomes.
• Rolling a number cube where one outcome represents one homeroom and the rest represent the fourth homeroom doesn't give 4 equally - likely outcomes for all homerooms.

Answer:

B. Draw a marble from a bag containing 5 white marbles, 5 black marbles, 5 red marbles, and 5 green marbles, with each color representing a different homeroom.
C. Use a random number generator with 1, 2, and 12 representing the first homeroom, 7, 9, and 10 representing the second homeroom, 3, 8, and 11 representing the third homeroom, and 4, 5, and 6 representing the fourth homeroom.
E. Spin a spinner with 8 congruent sections with 2 sections assigned to each homeroom.
