whether the marbles were selected with or without replacement.
Answer to Problem 26E
The answers are: a -selection without replacement, b -selection with replacement.
Explanation of Solution
Given:
Calculation:
The first diagram shows that in the first draw two marbles are drawn and in the second draw also two marbles are drawn. This implies that the marbles were not replaced. Because, there is one less marble in the second draw than the first draw. On the other hand, the second diagram shows that there are two marbles drawn in both the first and second draw. This shows that the second diagram follows the selection with replacement method.
Conclusion:
Therefore, the answers are: a -selection without replacement, b -selection with replacement.
