Develop a probability distribution for the points scored from spinning the following spinner. If you spin Red you get 4 points, if you spin Blue you get 3 points, if you spin Green you lose 6 and if you spin yellow you lose 6 points. Blue Red Green Yellow Red Blue What is the expected value of spinning this spinner? Is it a fair spinner? If you spin this spinner 25 times, what is the probability of getting red 10 times
