Sam 5 6 7 8 10 9 4 10 4 6 Silvie 8 5 7 5 2 9 10 4 5 9 If the sample space is all of the possible numbers of pins that can be knocked down in a single frame, which subset would be considered a complement of the set of pins that Sam and Silvie knocked down?
The complement of the set of pins that Sam and Silvie knocked down would be all the numbers of pins that were NOT knocked down by them.
In this case, the complement set would be all the possible numbers of pins from 0 to 10 that were NOT knocked down by Sam and Silvie in any frame. This includes numbers such as 1, 3, and 8, among others.
