The density function is defined like this case could be defined like probability of getting any number in the domain (0<=x<=2) is the same.
Let f(x) = k .................(1), be the density function, for o<=x<=2
Then f(x) = 0 for any other x .
Then for a density function, Integral f(x) dx should be 1 for x fro x=0 to x=2. Or
{Integral kdx from x=0 to x=2} should equal to 1.Or
{[(kx)atx=2]- [(kx) at x=0} should be equal to 1. Or
2k-0 =1 . Or
k = 1/2. Substitute this value of k in (1) .
Therefore, the uniform height of the curve (or ordinate of the curve) is f(x) = k Or f(x) = 1/2. Or y =f(x) = 1/2.
