After reading fantastic beasts and where to find them, your professor discovers that unicorns are equally likely to have 0, 1, 2, or 3 offspring. unfortunately, only one unicorn is left. that is, let (zn)∞ n=0 be a branching process that describes the population of unicorns at time n. the offspring distribution is uniformly distributed on {0, 1, 2, 3}, and z0 = 1. (a) find the probability that the population of unicorns will go extinct by the second generation. (b) find the probability that the population of unicorns goes extinct.

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

step-by-step explanation:

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
