Answer
Fᶜ is {0.4 Alice, 0.1 Brian, 0.6 Fred, 0.9 Oscar, 0.5 Rita},
Rᶜ is {0.6 Alice, 0.2 Brian, 0.8 Fred, 0.1 Oscar, 0.3 Rita}.
Work Step by Step
Assume that the universal set contains just Alice, Brian, Fred, Oscar, and Rita. We subtract the degrees of
membership from 1 to obtain the complement. Thus
Fᶜ is {0.4 Alice, 0.1 Brian, 0.6 Fred, 0.9 Oscar, 0.5 Rita},
and
Rᶜ is {0.6 Alice, 0.2 Brian, 0.8 Fred, 0.1 Oscar, 0.3 Rita}.
