GRB's occur once per day. over 10 billion years that's 3650 billion bursts (in the observable universe?). I think there are said to be around 100 billion galaxies in the observable universe so does that mean that 36 bursts occur in each galaxy?

I wonder how large a galaxy has to be before it has a supermassive black hole?
I wonder how many globular clusters there are and how that compares to the number 3650 billion?
