Solution Summary: The author calculates the monthly payments and total interest for a 120,000 mortgage at 4.5% for 30 years by substituting the values in the loan payment formula.
The temperature at a point (x,y,z) of a solid E bounded by the coordinate planes and the plane
9.x+y+z = 1 is T(x, y, z) = (xy + 8z +20) degrees Celcius. Find the average temperature over
the solid. (Answer to 4 decimal places).

Problem #5
Section A of my math class has 110 students. Section B of my math class has 80 students.
a). If I randomly select 15 students from the combined classes, in a way that the order of my
selection does not matter, what is the probability that all 15 students can from Section A?
b). If I randomly select 15 students from the combined classes, in a way that the order of my
selection does not matter, what is the probability that all 15 students can from Section B?
c). If I randomly select 15 students from the combined classes, in a way that the order of my
selection does not matter, what is the probability that all 7 students come from section A and 8
students come from section B?
