1)
P (A∪ B) = P(A) + P(B) – P(A∩B)
= 0.5 + 0.3 - 0 (A and B are mutually exclusive event hence P(A∩B)=0)
P (A∪ B) = 0.8
2) False

O PROBABILITY Probabilities involving two mutually exclusive events Events A and B are mutually exclusive. Suppose event A occurs with probability 0.03 and event B occurs with probability 0.02. a. Compute the probability that A does not occur or B does not occur (or both). b. Compute the probability that neither the event A nor the event B occurs. (If necessary, consult a list of formulas.) 6 2
Suppose that A and B are mutually exclusive and complementary events, such that P(A)=0.7 and P(B)=0.3. Consider another event C such that P(C/A)-0.2 and P(C/B)=0.3. What is P(C)?
Question 13 (2 points) If two events are mutually exclusive, then their probabilities can be added all of the choices are correct they may also be collectively exhaustive if one occurs, the other cannot occur the joint probability is equal to O Question 14 (1 point) The area under the normal distribution to the left of the mean is always 0.5 or 50 percent.
