Determine the value c so that each of the following
functions can serve as a probability distribution of
the discrete random variable
f(x) =c(x2+ 4), for x= 0,1,2,3;
(b)f(x) =c(choose x from2)(choose 3 from 3-x) for x= 0,1,2.
a flip on the y axis means a flip horizontally. if you look at point a which is (-4, -2) and make the x part of the ordered pair opposite, it becomes (4, -2).
15/16 = 0.9375
round 0.937 to 0.94
as we can see it's a geometric progression.
q = a2/a1
q = 1/3
an = a1 . q^(n - 1)
an = 3 . (1/3)^(n - 1)
the one which matches is f(n) = 3 . (1/3)^(n - 1)
functions can serve as a probability distr...
