*Mutually Exclusive Events(no outcomes in common)
P(A or B) = P(a) + P(b)
*Not mutually exclusive events(outcomes in common)
P(A or B) = P(a) + P(b) - P(a and b)
*Independent events(does not affect with each other event)
P(A or B) = P(a) x P(b)
*Dependent events(random selection without replacement)
P(A or B) = P(a) x P(b following a)

I hope my answers are correct :)
