If the Probability that a train arrives early is 0.09 probability late is 0.4 What is the probability it arrives on time?
The train can be either early, on time or late. The total probability must be 1. Thus: pr(early) + pr(on_time) + pr(late) = 1 0.09 + pr(on_time) + 0.4 = 1 => pr(on_time) = 1 - 0.4 - 0.09 = 0.51 Probability of being on time is 0.51
What is the describing of the complementary event and find its probability?
Suppose there is an event A and the probability of A happening is Pr(A). Then the complementary event is that A does not happen or that "not-A" happens: this is often denoted by A'.Then Pr(A') = 1 - Pr(A).Suppose there is an event A and the probability of A happening is Pr(A).

What is the difference between the multiplication rule for independent versus dependent events?
Given two events, A and B, Pr(A and B) = Pr(A)*Pr(B) if A and B are independent and Pr(A and B) = Pr(A | B)*Pr(B) if they are not.
What composite number can be expressed as product of its factors?
None.A composite number c must have a prime factor psuch that 1 < p < c.Therefore the product of c's factors must be at least p*c which must be greater than c.
If the product of a b and c is 0 and a and b are integers greater than 10 what must c equal?
if abc is 0 then at least one of the factors must be zero. since a and b are both nonzero, c must be zero.
