What is the difference between non-mutually exclusive event and a independent event?

Two non-mutually exclusive events mean that both can happen at the same time.
For example, you got a class of students of all gender and races. A is the probability of picking a male student and B is the probability of picking a chinese student. Both events are non-mutually exclusive as you can pick a student who is male and chinese at the same time.
Two independent events mean that their occurrence will not affect each other.
For example, A means throwing a 6 with a dice on the first throw, B means throwing a 3 with a dice on the second throw. No matter A happens or not, it will not affect the probability of B, hence they are independent events.
this should be on the first few pages of your probability notes
