Respuesta :

b) 4

c) 6

Answer:

see explanation

Step-by-step 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 }
