Abag contains 1 red and 7 white marbles. a marble is drawn from the bag, and its color is observed. then the marble is put back into the bag and the contents are thoroughly mixed. using (a) the binomial distribution, (b) the poisson approximation to the binomial distribution, find the probability that in 8 such drawings, a red ball is selected exactly 3 times.

Step-by-step explanation:

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
