Let's analyze the given contingency table to determine the marginal distributions for gold and diamonds.

[tex]\[ \begin{tabular}{|l|c|c|c|} \hline Ornaments & Gold & Diamond & Total \\ \hline Necklace & 532 & 689 & 1221 \\ \hline Ring & 131 & 482 & 613 \\ \hline Total & 663 & 1171 & 1834 \\ \hline \end{tabular} \][/tex]

### Marginal Distribution for Gold
The marginal distribution for gold means summing up all the counts of gold items irrespective of their type (necklace or ring).

- Number of gold necklaces: 532
- Number of gold rings: 131
- Total number of gold items: 532 + 131 = 663

So, the marginal distribution for gold is:
- 532 for necklaces
- 131 for rings
- 663 in total

### Marginal Distribution for Diamonds
The marginal distribution for diamonds means summing up all the counts of diamond items, again irrespective of their type (necklace or ring).

- Number of diamond necklaces: 689
- Number of diamond rings: 482
- Total number of diamond items: 689 + 482 = 1171

So, the marginal distribution for diamonds is:
- 689 for necklaces
- 482 for rings
- 1171 in total

Thus, the marginal distributions, expressed separately for gold and diamond items, are as follows:

1. Gold items:
- Necklaces: 532
- Rings: 131
- Total: 663

2. Diamond items:
- Necklaces: 689
- Rings: 482
- Total: 1171

### Selections
Based on the given question, the appropriate selections for the marginal distributions should include:
- 532 (Gold necklaces)
- 131 (Gold rings)
- 663 (Total gold items)
- 689 (Diamond necklaces)
- 482 (Diamond rings)
- 1171 (Total diamond items)

These values represent the marginal distributions for both gold and diamond ornaments according to the contingency table provided.
