The probabilty Distribution of a random variable X is given by the function
f(x)= 1/84 (5/x) (4/3-x) for x= 0,1,2,3
Calculate the numerical probabilities and list the distribution.
I got 10/21 for the x value of 2. The others I am unsure about! Help please
for x=2 I get:
1/84(5/2)(4/3-2)
= 1/84(5/2)(-2/3)
= -5/252
if the function is
f(x) = 1/84 (5/x) (4/(3-x)) for x = 2
= (1/84)(5/2)(4/1)
= 5/42
So first of all you must decide whether you typed it correctly.
