d. {1, 2, 3, 4, 5, 6, h, t}

Explanation:

Identify outcomes of individual stages

Using the Sample Space Outcomes knowledge point

• Die roll outcomes: \(D = \{1, 2, 3, 4, 5, 6\}\) (6 outcomes)
• Two coins outcomes: \(C = \{HH, HT, TH, TT\}\) (4 outcomes)
• Spinner outcomes: \(S = \{1, 2, 3\}\) (3 outcomes)

Calculate total outcomes in sample space

Using the Sample Space Outcomes knowledge point

• Total outcomes: \(6 \times 4 \times 3 = 72\)

Match with the correct option

• Option A lists elements of the form (Die, Coin1, Coin2, Spinner), such as \(1HH1, 1HH2, 1HH3, 1HT1, \dots\)
• Checking the count in Option A:
• For each of the 6 die numbers, there are 4 coin combinations (\(HH, HT, TH, TT\)), and for each coin combination, there are 3 spinner numbers.
• This yields exactly \(6 \times 4 \times 3 = 72\) unique outcomes.
• Option A correctly lists all 72 combinations.

Answer:

• (A) {1HH1, 1HH2, 1HH3, 1HT1, 1HT2, 1HT3, 1TH1, 1TH2, 1TH3, 1TT1, 1TT2, 1TT3, 2HH1, 2HH2, 2HH3, 2HT1, 2HT2, 2HT3, 2TH1, 2TH2, 2TH3, 2TT1, 2TT2, 2TT3, 3HH1, 3HH2, 3HH3, 3HT1, 3HT2, 3HT3, 3TH1, 3TH2, 3TH3, 3TT1, 3TT2, 3TT3, 4HH1, 4HH2, 4HH3, 4HT1, 4HT2, 4HT3, 4TH1, 4TH2, 4TH3, 4TT1, 4TT2, 4TT3, 5HH1, 5HH2, 5HH3, 5HT1, 5HT2, 5HT3, 5TH1, 5TH2, 5TH3, 5TT1, 5TT2, 5TT3, 6HH1, 6HH2, 6HH3, 6HT1, 6HT2, 6HT3, 6TH1, 6TH2, 6TH3, 6TT1, 6TT2, 6TT3} (Correct answer)
