Three coins are tossed. Describe Two events which are mutually exclusive but not exhaustive.
When three coins are tossed, the sample space is given by
$S =\{ HHH , \,HHT , \,HTH ,\, HTT , \,THH , \,THT , \,TTH , \,TTT \}$
Two events which are mutually exclusive but not exhaustive can be
$A:$ getting exactly one head
$B:$ getting exactly one tail
i.e.. $A=\{H T T, \,T H T, \,T T H\}$
$B =\{ HHT ,\, HTH , \,THH \}$
This is because $A \cap B=\phi,$ but $A \cup B \neq S$
Two numbers are selected randomly from the set $S = \{1, 2, 3, 4, 5, 6, 7, 8, 9, 10\}$ without replacement one by one. The probability that minimum of the two numbers is divisible by $3$ or maximum of the two numbers is divisible by $4$ , is
