I’m befuddled with ‘without replacement’ here. Isn’t the count of red ball and the total supposed to decrease if we are not putting any balls back?
My Solution:
P(Red Marble is Pulled out 1st) = 17/50
P(Red Marble is Pulled out 3rd) = (17-2)/(50-2) = 15/48
P(Red Marble is Pulled out 10th) = (17-8)/(50-8) = 9/42
I do not get how the probability stays the same, which is the correct answer.
