Question 19 • Concepts in Probability and Statistics A

Jaxon has a bag of marbles. He draws one marble from the bag. Before drawing another marble from the bag, what could Jaxon do to ensure that the events are independent of each other?

Answer
A
keep the marble he initially drew from the bag
B
return the marble he initially drew from the bag
C
add more marbles to the bag
D
remove all marbles that are the same color as the first one

Explanation

To make the draws independent, the result of the first draw must not change the chances of each outcome on the second draw. Jaxon can return the first marble to the bag, restoring the original group of marbles before drawing again. Therefore, the correct choice is “return the marble he initially drew from the bag.”
