Answer 2

Hey there !!
____________________________________

Number of girls standing in a line = 13
Number of boys standing in a line = 15

Total no. of students in a line = 13 + 15 = 28

Now, finding the probability

P ( getting a boy ) = Number of outcomes favourable to the event / Number of all possible outcomes of the experiment

= 15 / 28
