The complement involves probability. Say the probability of choosing a red marble was 3/10. So the complement, or the chance of not choosing a red marble is 7/10. Think of it as the opposite of the probabilty. You simply subtract the numerator from the denominator and you have the complement. (10-3=7 in this case, then you would put your difference over the probabilities denominator, so it would be 7/10.)
80 degrees is the complement of 10 degrees, as both angles combined must be 90 degrees, a right angle.
Why? Because that's what "complement" means. For example, if 60% of a certain population are adults, the remainder - 40% - are not adults. That's the complement. The "100%" refers to the total population in this case.
50% is its own complement.

what is the verb complement
The complement of a number is what needs to be added to make a specific value. Typically when dealing with complements of a number a base of 10 is used (complement of 9 is 1 since 9 +1 = 10). In the case of four tenths, the complement would be 6 tenths 4/10 + 6/10 = 10/10 or 1

65% (35+65 = 100%)
It is better to do this with a venn diagram and I suggest drawing one. A is liking chips B is liking peanuts A intersect B is liking both. A union B is liking either peanuts or chips or both We want the complement of A union B which is A complement intersect B complement by DeMorgans law. A complement is not liking chips B complement is not liking peanuts Now if we add 25+45 and then subtract 10 that will be the percent that like chips or peanuts but NOT both and this is 60 percent. This is P(A) union P(B)-P(A intersect B) The negation of this is those who do not like chips and do not like peanuts-(those who don't like both) Since the total is 100%, 100%-60% is 40% 40% do not like either. You could also reason that there must be 15 % who like only chips and 35 percent who like only peanuts since 15%+10%=25% and 15%+10%=45. So the number who like either chips or peanuts but NOT both is 15+35=60 Now the number who like neither is 100-60 or 40% 40% is A complement intersect B complement.
