n > (-1) since its an integer n is >= 0 but that doesnt tell anything abt p
From 2 Alone
I get nothing interesting
Combining 1 and 2
If np >0 and we know that n >=0 so then n has to be > 0 and p also has to be > 0
Hence Combining both we get the answer

Thanks for the answer
sometime I forget some very important details. Here I forgot n is an integer thus n > -1 is the same as n >=1...
