Given two random variable X and Y and their joint distribution P(X,Y):

P(X,Y): 2 4 6
Sensor 1 0.22 0.17 0.03
Sensor 2 0.15 0.1 0.11
Sensor 3 0.06 0.16 0

Find following measures:

g.H(Y)-H(Y|X),
h.I(X;Y)
i. If X is the number of senores on a vehicle and Y is the battery level of the vehicle, what does
I(X;Y) tell us? (let’s say we can observe the number of senores easily but not the battery level)
