Hi everyone,

I am a new member in the forum. I am still confused with the concept of conditional entropy:

For example H(x|Y)= H(x, y) - H(x) which is again will be H(y) right???

for example: I have this problem:

P(y)= (0.23, 0.29, 0.84) and P(x)= (0.2, 0.4, 0.4)

I get H(X)= ~1.5217 bits and H(y)=~ 0.773 bits.

So how can I determine the value of H(x|Y)

Thanks in advance
