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 dice are thrown. The events $A, B$ and $C$ are as follows:
$A:$ getting an even number on the first die.
$B:$ getting an odd number on the first die.
$C:$ getting the sum of the numbers on the dice $\leq 5$
Describe the events not $B$
From the word `$POSSESSIVE$', a letter is chosen at random. The probability of it to be $S$ is

A bag $x$ contains $3$ white balls and $2$ black balls and another bag $y$ contains $2$ white balls and $4$ black balls. A bag and a ball out of it are picked at random. The probability that the ball is white, is
An experiment consists of tossing a coin and then throwing it second time if a head occurs. If a tail occurs on the first toss, then a die is rolled once. Find the sample space.
