Question

What is the sample space for choosing 1 marble at random from a jar containing 5 red, 7 blue, and 2 green marbles?

Answer 1

Answer:  a) { red, blue, green}

Reason: We can only get one outcome, and that outcome could be a red, a blue, or a green marble. We only list one unique item at a time. The order doesn't matter. The sample space represents all possible outcomes.
