Toolbox:
  • If there is only one sample point,it means it is a simple point.
Given three coins are tossed.
Therefore,the sample space (ie) $2^3=8$ possible outcome
$S=\{HHH,HHT,HTH,HTT,THH,THT,TTH,TTT\}$
Given :
A=Three heads shows ={HHH}
B=Two heads and one tail show ={HHT,HTH,THH}
C=Three tail show ={TTT}
D=A head shows on the first toss={HHH,HHT,HTH,HTT}
Events A,C have only one sample point .Therefore,A and C are simple events.
