When three coins are tossed, the sample space is given by

$S =\{ HHH , \,HHT , \,HTH ,\, HTT , \,THH , \,THT , \,TTH , \,TTT \}$

Two events that are not mutually exclusive can be

$A:$ getting three heads

$B:$ getting at least $2$ heads

ie. $A=\{H H H\}$

$B =\{ HHH , \,HHT , \,HTH ,\, THH \}$

This is because $A \cap B=\{H H H\} \neq \phi$
