View answer resolution
【Answer to question 1】C
【analysis】
C is correct. The two defining properties of a probability are as follows:
1 The probability of any Event E is a number between zero and one.
2 The sum of the probabilities of any set of mutually exclusive and exhaustive events equals one.
A is incorrect because the probability of any event E is a number between 0 and 1.
B is incorrect because the probability of any event E is a number between 0 and 1.
【Answer to question 2】C
【analysis】
C is correct. When two events are independent, the events are unrelated and the probability of occurrence of one event does not affect the other.
A is incorrect because when two events are independent, the joint probability of both events, not one event, equals the product of the individual probabilities of both events.
B is incorrect because an event is considered dependent when the probability of occurrence of one event is related to the occurrence of the other event.
成功=时间+方法，自制力是这个等式的保障。世上无天才，高手都是来自刻苦的练习。而人们经常只看到“牛人”闪耀的成绩，其成绩背后无比寂寞的勤奋。小编相信，每天都在勤奋练习，即使是一点点的进步，大家一定可以成为人人称赞的“牛人”。更多CFA考试资讯，点击了解>
