Probability With Replacement

[nycmathguy]

A bag has 4 red marbles, 3 green marbles and 6 yellow marbles. You select 2 marbles from the bag with replacement. Determine the probability the first marble is red and the second marble is green.

total:13 marbles
P first marble is red and the second marble is green
(4/13)(3/13)=12/169=0.07101 or 7.101%

This probability stuff is something I would like to learn later on in my studies. Always had trouble understanding the fuzzy questions.
