Answer 1

So there's an 1 in 4 chance that you will get a red marble in the beginning. You draw it, then take it out. After you draw the first marble, you now have a 1 in 5 chance that you'll get another red marble. What you want to solve is what's the chance that you'll get two consecutive red marbles.

\[\frac{ 1 }{ 4 } \times \frac{ 1 }{ 5 }\]
