Four cutting machines are selected from a large lot of damaged
machines. Each machine is inspected and classified as containing
either a major or a minor defect. Let the random variables X and Y
denote the number of machines with major and minor defects,
respectively. Determine the range of the joint probability
distribution of X and Y.
a.
X >= 0, Y >= 0 and X + Y = 5
b.
X >= 0, Y >= 0 and X + Y = 4
c.
X >= 1, Y >= 1 and X + Y = 5
d.
X >= 1, Y >= 1 and X + Y = 4
