Question 839339: You have a box that contains 10 blue cubes and 5 red ones.
1. What is the probability of a randomly selected cube being red? 5/15= 1/3
2. What are the ODDS of it being blue? 10:15= 2:3
3. If the cubes are not replaced after each selection, what is the probability of getting 3 blue cubes in a row? 2/3*9/14*8/13= 144/546=24/91
4. If the cubes are replaced after each selection, what is the probability of selecting a red one followed by a blue one? 1/3*2/3=2/6=1/3
5. What is the probability of selecting a blue cube, then a red one, then a blue one? 2/3*1/3*2/3= 4/27
