What is the difference between experimental and theoretical probability?
Experimental is what does happen, theoretical is what should happen

What is the difference between a dependent and independent event?
Independent: when the outcome of one event does not impact the outcome of the second event
Dependent: When the outcome of one event impacts the outcome of another
