I need to find k for the probability distribution:
P(x)=k(x+2) for x=1,2,3

I tried subbing in the x-values, which gave me:
P(1)=3k
P(2)=4k
P(3)=5k

But I still have no idea what I need to do to find k.

Guidance, please?

  • Math -

    Are you sure you were asked to find k?
    I don't see how you can find k with the
    INFO given. You found P(x); i don't see
    how you can do anymore.
