In this question, there is supposed to be a chart.

First Flip        Second Flip        Third Flip

    T                       T                         T

    T                       T                         H

    T                       H                        T

    T                       H                         H

    H                      H                         H

    H                      H                        T

    H                      T                         H

    H                      T                         T

                            Key

                        T = Tails

                        H= Heads

Since this chart has eights rows, and the question is saying "at least 1 heads", then there is one out of eight (1/8) chances to get a heads.
