Answer:
Sue has a 12% chance of choosing a black dress and a gold necklace (as a fraction: 3/25, and as a decimal: 0.12).
Step-by-step explanation:
To find the probability of two separate events both occurring (in this case, selecting a black dress and a gold necklace), the probabilities are multiplied usually as fractions or decimals.
<u>As fractions:</u>
40% = 4/10
30% = 3/10
4/10 * 3/10 = 12/100 = 3/25, 0.12, or 12%
<u>As decimals:</u>
40% = 0.4
30% = 0.3
0.4 * 0.3 = 0.12 = 3/25, 0.12, or 12%
