32. What probability value would be needed to complete the following probability distribution?
x -5 -1 0 1 4
P(x) 0.13 0.25 0.12 0.30

For a probability distribution, we have

Thus the P(X=1) = 1-P(X=-5)-P(X=-1)-P(X=0)-P(X=4) = 1-0.80 =0.20

25. An apartment building has the following apartments:
1 bedroom 2 bedroom 3 bedroom
