Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

explain portion in red color
meaning of this part is that..... when we change x into -x , y into -y and so on that will not chnz the integral because here sqaure if the integral is taken care. also our x^2+y^2+z^2 should be less then one because if it is not so then our integral will become imaginary. and that's not the situation demands.
