Průnik množin A a B
Jsou dány množiny A = \{1;4;7;9;12 \} a B = \{–3;0;2;4 \}.
Urči:
\large A \cap B
\large A \cap B = \left \{4 \right \}
\large A \cap B = \left \{9 \right \}
\large A \cap B = \left \{1 \right \}
\large A \cap B = \left \{7 \right \}
Budeš dělat průnik dvou množin. Průnik spočívá v tom, že hledáš společné čísla obou množin.
