Asmall class has 9 students, 3 of whom are girls and 6 of whom are boys. the teacher is going to choose two of the students at random. what is the probability that the first student chosen will be a boy and the second will be a girl? write your answer as a fraction in simplest form?

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
