they are events that can't occur at the same time. For example, you toss a coin you get head or tails. These are complementary events since you can't have both at the same time, only one!
Complementary events are the events where you are considering all of the other outcomes that you don't want. For example, Let's say you are rolling a die and you want to find all the odd # rolls. When you get a result of an even number, then you would put it aside as a "complementary event", for it is a result that you don't want.
no
Yes, they are. Mutually exclusive events cannot occur together. Complementary events cannot occur together either because an event and its complement are the negative of each other.

an educated guess about the results of certain events or actions
Complementary events are events that are the complete opposite. The compliment of event A is everything that is not event A. For example, the complementary event of flipping heads on a coin would be flipping tails. The complementary event of rolling a 1 or a 2 on a six-sided die would be rolling a 3, 4, 5, or 6. (The probability of A compliment is equal to 1 minus the probability of A.)
These events are said to be complementary.
Complements or complementary events
Yes, the definition of complementary angles is that their sum is 90 degrees. All 90 degree angles are by definition right angles.
The term 'complementary' is an adjective, or descriptive word used to define one or more nouns. Although there are several meanings of 'complementary' the basic definition is "serving to complete." It's usually applied to nouns that in some way go together.
If an event is absolutely certain to happen is then we say the probability of it happening is 1.Complementary events are such that one of the events musthappen. Therefore the probability of one of a set of complementary events occurring is 1.For instance : The probability that a fair coin when tossed will come down showing heads is 1/2, and that it will show tails is also 1/2.The two events are complementary so the probability that the coin toss will result in either a heads or a tails is 1.Similarly, the probability that a die when rolled will show a number 1, 2, 3, 4, 5 or 6 is 1 as all six events are complementary.
