Best ResponseYou've already chosen the best response.0Complementary events are like 1/2 or like flipping a coin and getting heads or tails, rite?

Best ResponseYou've already chosen the best response.1almost, two sets are complementary when they add up to the entire sample space of events say the universal set is: U={a,b,c,d,e} let setA = {a,b,c} the complement of A is the set UA = {d,e} A combined with its complement form the Universal set.

Best ResponseYou've already chosen the best response.1In probability, the universal set of the sample space, is 1 so the probability of the complements added up will have to equal what?

Best ResponseYou've already chosen the best response.0I dunno. I'm sorry, but I don't get most of what you're trying to say.

Best ResponseYou've already chosen the best response.1what is the probability of an entire sample space?

Best ResponseYou've already chosen the best response.0That would be...1, rite?

Best ResponseYou've already chosen the best response.1yes and complements are events that are mutually exclusive (what does this mean?) that add up to the entire sample space.

Best ResponseYou've already chosen the best response.1and yes, its A ... 4/11 + 7/11 = 1, and gold cannot be silver so they are mutually exclusive.
