True or False

Tell Whether It's True or False Based on the Situation
True or false. If E and F are mutually exclusive, and E and G are mutually exclusive, then F and G are mutually exclusive.
True or false. Suppose it is determined that the probability of obtaining heads in a coin- tossing experiment using a biased coin is 0.51, then the probability of obtaining tails in a toss of the coin is 0.49.
True or false. Suppose S = {s1, s2, …, sn} is a finite sample space with n outcomes. Then 0 < P(s1) + P(s2) + … +P(sn) < 1.
True or false. P(E) + P(Ec) = 1.
True or false. P(Ec ∪ Fc) = 1 - P(E ∩ F)
True or false. If A and B are events in an experiment and P(B) ≠ 0, then 20140305033613equation.png
