The probability that a randomly chosen senior played football at the tournament is approximately 0.2167 or 21.67%.
To find the probability that a randomly chosen senior played football at the tournament, we need to divide the number of seniors who played football by the total number of seniors.
In this case, there were 13 seniors who played football and a total of 60 seniors. So, the probability is:
P(football) = Number of seniors who played football / Total number of seniors = 13 / 60 = 0.2167 (rounded to four decimal places).
Therefore, the probability that a randomly chosen senior played football at the tournament is approximately 0.2167 or 21.67%.
