2. a) At a meeting of the International Astronomical Society, 45% of the attendees are females and 30% are teachers. Given that an attendee is a teacher, 55% are females. What is the
probability that a randomly selected attendee is both a teacher and a female?
b) A MTH 20 class consists of 52% males, 65% liberal arts majors, and 41% who are both
males and liberal arts majors. Find the probability that a randomly selected student in the
class is either a male or a liberal arts major.

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
