ILLUSTRATING UNION OF EVENTS

If A = { 5, 6, 7 } and B = { 6, 8, 10 }, what is A U B ?

 $If\ \ A\ =\left\{5,6,7\right\}\ and\ B\ =\ \left\{6,8,10\right\}\ ,\ what\ is\ \ A\ \cap\ B\ ?$  

 $If\ \ M\ =\left\{a,\ b,\ c\right\}\ and\ N\ =\ \left\{b,c,d\right\}\ ,\ what\ is\ \ M\ \cap\ N\ ?$  

 $If\ \ M\ =\left\{a,\ b,\ c\right\}\ and\ N\ =\ \left\{b,c,d\right\}\ ,\ what\ is\ \ M\ \cup\ N\ ?$
