Given the following Samples: x1 : X= 80, y =1, x2: X=20, y =1 , and x3: X = 120 y = 0

How should i go about these questions ?

1) Calculate the probability that y = 1 for each 𝑥0 of the data set (h𝜽 𝑥 )

2) Calculate the value of objective (cost) function based on idea of SSE

3) Calculate the value of objective (cost) function based on log of Sigmoid

Not sure how to go about these, so any help would be appreciated!
