The union of two sets includes all unique elements from both sets.
In your case, the results of your spins are:
You: {red, yellow, red, orange, orange, red} → unique colors: {red, yellow, orange}
Your friend's spins are:
Friend: {blue, red, orange, purple, purple, red} → unique colors: {blue, red, orange, purple}
Now, to find the union of your results and your friend's results:
Union = {red, yellow, orange} ∪ {blue, red, orange, purple} = {red, yellow, blue, orange, purple}

{red, blue, yellow, orange, purple}
So, the answer should be:
{red, blue, yellow, orange, purple} (left brace red comma blue comma yellow comma orange comma purple right brace)
