When Ryan walks into the auditorium, there are 5 available seats in the first row, 10 in the second row, and 2 in the third row.

Ryan randomly selects a seat.

What is the probability, to the nearest percent, that his seat will be in the first row?

29%! There are a total of 17 seats, and since there are 5 seats in the first row, you are going to divide 5 by 17 and that gives you 0.2 94117647 which you will round to. 29 and you have your answer. The probability that Ryan's seat will be in the first row is 29%!
