Answer:
1/100
Step-by-step explanation:
Step 1: The probability of picking 1 marker out of 100 is 1/100. The marker is now kept back. For now, that's the only marker that we had.
Step2: The box now contains only 1 marker that we have to pick out of 100. The probability of picking 1 marker out of 100 is 1/100 and that's you answer.
This isn't a successive probability problem in my opinion.
