What is the sample space for choosing 1 marble at random from a jar containing 5 red, 7 blue, and 2 green marbles?
1 answer:
<h3>
Answer: a) { red, blue, green} </h3>
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.

D. 7(x − 10)(y + 2) = 7xy + 14x − 70y − 140 (Wrong)
