The expected value of a discrete random variable a. is the most likely or highest probability value for the random variable. b. will always be one of the values x can take on, although it may not be the highest probability value for the random variable. c. is the average value for the random variable over many repeats of the experiment. d. is the value it is expected to assume in the next trial.

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
