A survey was done asking how many students upon campus enjoy cardio and lifting weights. The survey found that 60% enjoyed lifting weights, 37% enjoy doing cardio, and 18% enjoy doing both.
1. What percentage of students don't enjoy lifting weights NOR enjoy doing cardio?
2. Are C and D mutually exclusive events? Why or why not?
3. Are the two events, C and D, independent? Explain, using probabilities.
4. If we know someone enjoys doing cardio, what is the probability they also enjoy lifting weights?
