Probability Experiment In Exercises 51-54, a probability experimen consists of rolling a six-sided die and spinning the spinner shown at the left. The spinner is equally likely to land on each color. Use a tree diagram to find the probability of the event. Then tell whether the event can be considered 51. Event A: rolling a 5 and the spinner landing on blue 52. Event B: rolling an odd number and the spinner landing on green 53. Event C: rolling...
