Question 620836: a bag contains 6 red cubes and 6 blue cubes. If the first cube is randomly picked and put back, what is the probability that both cubes are red?

You can put this solution on YOUR website! Hi, there--
.
You have a bag with 12 cubes; 6 of them are red. The probability of getting a red cube on the first draw is 6/12, or 1/2.
.
You replace the cube, so the probability is the same on the second draw, 6/12, or 1/2.
.
So the probability of drawing two red cubes, with replacement, is (1/2)*(1/2)=1/4.
.
Hope this helps! Feel free to email if you still have questions about this.
