This is the table. Blue is the probability, red is the z-value

Oh ok but is it always 0 if the probability is 0.5?
That table is for the standard Normal distribution N~(0,1)
p(x<μ) = 0.5 for all Normal distribution since the curve is symmetrical about the mean, ie x=μ
So no, it's not always 0.

Oh ok thank you
