  • If there is atleast two or more sample points,then the event is compound.
Given three coins are tossed.
Therefore,the sample space (ie) $2^3=8$ possible outcome
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 B,D have two or more sample point.
Therefore B and D are compound events
