Question

I’m stuck on this entire problem.

Answer 1

A) No, because your bag has 8 marbles, and each time you take it out, you put it back in. So there is a chance that you can pick the same marble again, and not pick up a red marble that's already in the bag.

b) No, because you could still keep on picking up the same marble over and over again.

c) There is no absolutely certain number of times.
