Ms. Hudson lets each student choose a marble from a bag with 2 yellow, 1 green, 3 red, and 3 blue marbles. If the student chooses a green marble, they receive a homework pass. What is the sample space?

{Y, G, R, B}
{B, B, B, R, R, Y, G}
{R, R, R, B, B, G, Y}
{Y, Y, G, R, R, R, B, B, B}

1 answer

To find the sample space of the marble selection from the bag, we need to list all possible outcomes based on the number and types of marbles present.

The bag contains:

  • 2 yellow marbles (Y)
  • 1 green marble (G)
  • 3 red marbles (R)
  • 3 blue marbles (B)

The total outcomes are made by considering each colored marble as a unique outcome. Therefore, the sample space is:

  • 2 yellow: Y, Y
  • 1 green: G
  • 3 red: R, R, R
  • 3 blue: B, B, B

When we list all the marbles, we get:

  • Y, Y, G, R, R, R, B, B, B

The correct representation of the sample space is: {Y, Y, G, R, R, R, B, B, B}

Thus, the correct answer is: {Y, Y, G, R, R, R, B, B, B}
