Usando conjuntos de Venn, se encuentra que 7 estudiantes practican solo atletismo.

Los conjuntos son:

  • Conjunto A: Estudiantes que practican natación.
  • Conjunto B: Estudiantes que practican atletismo.

Hay que:

  • 13 que practican natación, o sea, A = 13.
  • 10 practican atletismo, o sea, B = 10.
  • 2 que no practican nada, o sea A \cup B = 22 - 2 = 20.

La cantidad que practica ambos es:

A \cap B = A + B - A \cup B

A \cap B = 13 + 10 - 20

A \cap B = 3

Solo atletismo es:

B - A \cap B = 10 - 3 = 7

7 estudiantes practican solo atletismo.
