# Question: Consider the events not J H I H

Consider the events (not J), (H & I ), (H or K), and (H & K) discussed in Problem 11.

a. Find the probability of each of those four events, using the f/N rule and your answers from Problem 11.

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

c. In Problem 13(a), you found that P(H) = 0.535 and P(K) = 0.321; and, in part (a) of this problem, you found that P(H & K) = 0.214. 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).
