Let's break down the information given:
1. In the first round, 40% of 50 members win, which is 0.4 x 50 = 20 members.
2. In the second round, 75% of the members from the previous round win, which is 0.75 × 20 = 15 members.
3. In the fourth round, 9 members are still in the competition.
Now, let's find out how many members were in the third round:
Members in 3rd round = 0.75 × Members in 2nd round = 0.75 × 20 = 15
今78%口

To find the percentage of the Tabletop club members in the 3rd round who win their 3rd round matches, we need to compare the number of winners in the 4th round (9 members) to the total number of members in the 3rd round (15 members):
Percentage = (i × 10
Now calculate the percentage.
