Answer» 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

Answer»

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
