For each of the following problems, you should write your answer as an expression. Do not
give the final numeric value. For example, if your answer is the number of
6-permutations of a set with 10 elements, you should write P(10,6) or 10!/4! or 10 × 9 × 8 ×
7 × 6 × 5, but not 151200.
4.
Given the equation v+w+x+y+z = 151, where v, w, x, y, and z are
integers, how many different solutions does this equation have if……
4.1...all the variables must be positive?
4.2 ...v > 5, w > 10, x > 15, y > 20, and z > 25?
