f(y) is a discrete random density function where

f(y)= 1/2 at the interval of (1,2)
1/4 at [4,6]
find (and graph if you can) the F(y) Distribution function

Question

f(y) is a discrete random density function where

f(y)= 1/2 at the interval of (1,2)
         1/4 at [4,6]
find (and graph if you can) the F(y) Distribution function

perl · Answer

i would graph it, and then add up the areas under the curves

anonymous · Answer

where I got confused is 1/2 is between 1 and 2 but not on 1 or to being discrete does it count?

perl · Answer

i mean, first graph f(y), then graph F(y) , the accumulation function

perl · Answer

basically F(Y) = integral f(y) , from a to x

anonymous · Answer

1/4 from 4,5,6 so in this interval I get 3/4 and still need 1/4 more for it to become 1,
The number doesn't add up

anonymous · Answer

There was a similar problem with this in the book, considering that it is discrete I don't think I'm suppose to integrate.
