Min(0,X) 0 represents what ? You might want to add something?

the minimum of 0 and X

That is min, I am asking 0 Is it another variable Y (normal variable which is 0)

oh, I see where I should've explained more. the normal distribution has a mean of zero (0). and therefore A is equal to the minimum of the mean of the distribution and X and B is the maximum of the mean and X

apologies for not being more clear about the mean there

Thanks for the clarification now.
