Answer:

Step-by-step explanation:

Hi ,

_____________________________________________________________

The theoretical ( classical ) probability of an event  E , written as P(E),

its define as  

P(E) = ( Number of outcomes favorable to E) / ( Number of all possible

                                                          outcomes of the experiment )

____________________________________________________________

According to the problem ,

Number of girls in the line = 13

Number of boys in the line = 15

Total possible out comes = Number of girls + Number of boys

                                        = 13 + 15  

                                        = 28 -------( 1 )

The number of outcomes favorable for one student is chosen at  

random that probability that he is a boy = 15 ---------( 2 )

P (  boy ) = ( 2 ) / ( 1 )  

                         = 15 /28

I hope this helps you.
