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

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.
