Adjusted Gross Incomes. Consider the events (not J ),

(H & I), (H or K), and (H & K) discussed in Problem 31.

a. Find the probability of each of those four events, using the f/N rule and your answers from Problem 31.

b. Compute P(J ), using the complementation rule and your answer for P(not J ) from part (a).

c. In Problem 33(a), you determined that P(H) = 0.528 and P(K) = 0.345; and, in part

(a) of this problem, you found that P(H & K) = 0.217. Using those probabilities and the general addition rule, find P(H or K).

d. Compare the answers that you obtained for P(H or K) in parts (a)

and (c).
