    The total area of the rectangular seating chart is 10in * 14in=140 in squared.

    The area of one square of dimensions 2 in by 2 in is 4 in squared.

    Thus, there are a total of 140/4=35 squares, which means 35 student names on the seating chart.

    The probability of choosing a certain student the first time is 1/35=0.029.

    The probability that that particular student is not chosen is 34/35=0.97.

    Thus, the probability that the student is chosen the first time, and not chosen the second time is 0.029*0.97=0.028.

    Answer: 0.028
