There are different formulas for calculating the two types of compound events: Say A and B are two events, then for mutually exclusive events: P(A or B) = P (A) + P(B). For mutually inclusive events, P (A or B) = P(A) + P(B) - P(A and B).
The answer is 492.307
The number after the thousandths is 9 - greater than 5 - so we round 6 up to 7.
I hope you understand....
