marysya [2.9K]

Answer:

The sample space is:

  • (T,N): table height and brown
  • (T, W): table height and white
  • (T, K) : table height and black

  • (B, N): bar height and brown
  • (B, W): bar height and white
  • (B, K): bar height and black

  • (X, N): XL height and brown
  • (X, W): XL height and white
  • (W, K): XL height and black

Explanation:

The <em>sample space </em>is the set of all the possible outputs, i.e. the possible different combinations that can be choosen.

Use the letters T, B, and X to represent, respectively, table height, bar height, and XL height,

Use letters N, W, and K to represent, respectively, the colors brown, white and black.

Each combination consists of a height (T, B or X) and a color (N, W, K); thus, your sample space shall have 3 × 3 different combinations. These are:

  • (T,N): table height and brown
  • (T, W): table height and white
  • (T, K) : table height and black

  • (B, N): bar height and brown
  • (B, W): bar height and white
  • (B, K): bar height and black

  • (X, N): XL height and brown
  • (X, W): XL height and white
  • (W, K): XL height and black
