Thanks so much for your replies:

Infarction, actually, i just wrote a sample code that i was trying.

Sorry, forgot to add my code as per the rules.

And also, missed one part, i want inverse of the sum of random numbers which is less than 1 but greater than 0.75
such as :
sum = 1/23+1/32......

Hi,
Would really appreciate if someone can help me.

Need to generate 10 random numbers such that their sum is less than 1.

thanks so much in advance
