In the paper Advanced LIGO they published some figures with chances. I would like to know how they know that there's a 90% chance for something to be in a specific value.

paper here
also have some other questions:
What is a quadruple moment? (not too much terminology please)
How can you derive that from the formula, that if the chirp mass = 30 solarmasses that m1+m2 = 70 solarmasses ? (it says this in the paper with the formula for the chirp mass)
Due to what are the following noises created?
Quantum noise
Test mass thermal noise
Suspension thermal noise
Gravity gradients
