Answer:
see explanation
Explanation:
Given x ∈ { 2, 3, 4, 5, 6, 7, 8, 9, 10 }
Factors of 10 are 1, 2, 5, 10, thus
P = { 2, 5, 10 } ← 1 is not a member of the universal set
and the number of elements in P , that is n(P) = 3
The complement of P is the elements not in P but in the universal set
P' = { 3, 4, 6,7,8,9 }
