Find the sum of the first 10 terms of each arithmetic sequence. $$5,9,13, \dots$$

The table gives the results of a survey of \(14,000\) college students who were cigarette smoker in a recent year. \begin{array}{l|c}\hline \text { Number of Cigarettes per Day } & \text { Percent (as a Decimal) } \\\\\hline \text { Less than 1 } & 0.45 \\\1 \text { to } 9 & 0.24 \\\10 \text { to } 19 & 0.20 \\\\\text { A pack of 20 or more } & 0.11\end{array} Using the percents as probabilities, approximate the probability that, out of 10 of these student smokers selected at random, the following were true. Five smoked a pack or more per day
