 no tails

Answer 1

\[\text{ When 3 coins are tossed together, the outcomes are as follow }: \]
\[S = \left\{ \left( h, h, h \right), \left( h, h, t \right), \left( h, t, h \right), \left( h, t, t \right), \left( t, h, h \right), \left( t, h, t \right), \left( t, t, h \right), \left( t, t, t \right) \right\}\]
\[\text{ Therefore, the total number of outcomes is 8 } . \]
