Suppose event A occurs with probability 0.2 and event B occurs with probability 0.18. a. Compute the probability that A does not occur or B does not occur (or both). b. Compute the probability that either A occurs without B occurring or B occurs without A occurring. (If necessary, consult a list of formulas.) b. Clear Undo Help Next >> Explain

Explanation / Answer

P(A) = 0.2

P(B) = 0.18

P(A and B) = 0

P(A or B) = 0.2 + 0.18 = 0.38

P(not A or not B) = P(not A) + P(not B) - P(not A and not B)

P(not A or not B) = (1-0.2) + (1-0.18) - P(not(A or B))

P(not A or not B) = 0.8 + 0.82 - 1+0.38 = 1
