If random variables X and Y satisfy: P{X=-2,Y=-1}=1/6, P{X=2,Y=-1}=1/6, P{X=-2,Y=0}=1/3, P{X=2,Y=0}=1/6, P{X=-2,Y= 1}=1/24, P{X= 2,Y= 1}=1/8. Then, the joint entropy of X and Y is ____________, the conditional entropy of X given {Y=0} is ____________ and the entropy of X is _____________. (Notice: 2 deci. for example, 23.34bit/symbol)
