Understanding N(d2) of Black Scholes

Understanding the N(d2) is quite important as it is not only required in option pricing but also required to value debt and model probability of default which is very much prevalent in the part 2 curriculum.
I learnt a lot from here, anybody can have a look

Yes - I think most of this is already captured in David's work below.

Thanks @arkabose that's interesting, I like his site (I follow it). For myself, I don't exactly find his derivation highly intuitive because I don't think it's a strong picture on the connection between the asset price distribution and the Z-score. But that's just my opinion. FWIW, here is an old video I did on understanding N(d2) as a variation on Merton's PD = N(-DD), but it's all in the same link that @Mkaim provided. Thanks!
