Question

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

a) { red, blue, green}
b) { 5 red, 7 blue, 2 green }
c) { 5, 7, 2 }
d) None of the above

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.
