तीन सिक्के एक बार उछाले जाते हैं। वर्णन कीजिए।
दो घटनाएँ जो परस्पर अपवर्जी नहीं हैं।

Option B
Option C
Option D
Solution
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 $A \cap B=\{H H H\} \neq \phi$
