Short Answer

The following numbers were randomly generated. Starting with the number 97 , select every other number down the columns, continuing at the top of the next column, until seven numbers have been chosen. If the odd numbers represent tails, and the even numbers represent heads, how many times does this simulated coin land on tails?
$\begin{array}{lllllllll}68 & 96 & 37 & 69 & 97 & 19 & 50 & 29 & 66 \\74 & 8 & 58 & 5 & 13 & 30 & 69 & 65 & 50 \\36 & 47 & 22 & 15 & 19 & 44 & 9 & 11 & 16\end{array}$
