Answer

The sample space is $S=${$HHH; HHT; HTH; HTT; THH;THT;TTH;TTT$}

Work Step by Step

During coin flip experiments we use the letter $H$ for heads and letter $T$ for tails. The sample space is a set that consists of all the possible results of the experiment. Here, each of the three coins can be heads or tails up after landing. Therefore there will be $2\times2\times2=8$ possible outcomes. The sample space is $S=${$HHH; HHT; HTH; HTT; THH;THT;TTH;TTT$}
