Please help me with this problem from Galaxies in the Universe: an introduction. The problem is shown in the images.
Problem 2. 1 1 Here you make a numerical model describing both the distributionof stars and the way we observe them , to explore the Malmquist bias . If we observestars down to a fixed apparent brightness , we do not get a fair mixture of all thestars in the sky , but we include more of the most luminous stars . This methodof “Monte Carlo simulation ” is frequently used when a mathematical analysiswould be too complex .( a ) Your model sky consists of G- type stars in regions A ( 70 pc < d < 90 PC ).B ( 90 pc < < < 1 10 p0 ), and C ( 1 10 pc < < < 130 pc ). If the density is uniform ,and you have ten stars in region B , how many are in regions A and C ( round to
