1. Think more about the probability of each event. Put numbers on each of the 8 prophecy fulfillments. Some of the probabilities will be subjective‚ but put values that you feel make sense. Do not put probabilities of 0 or 1. Given the new probabilities you associated with each prophecy‚ what is the probability that all 8 happened in sequence? 1. Bethlehem was one of the smallest cities in the land of Judah. This means that out of the 1 million or so people that lived in Judah‚ only around

Page 4 :INTRODUCTION Definition: Probability is the study of chance or the likelihood of an event happening. Directly or indirectly‚ probability plays a role in all activities. Probability is a measure or estimation of how likely it is that something will happen or that a statement is true. Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen). The higher the degree of probability‚ the more likely the event is to happen‚ or‚ in a longer series

1 Introduction of Probability Instructor: 1. In a poll‚ respondents were asked if they have traveled to Europe. 68 respondents indicated that they have traveled to Europe and 124 respondents said that they have not traveled to Europe. If one of these respondents is randomly selected‚ what is the probability of getting someone who has traveled to Europe? Outcome: selecting someone who has been to Europe 68 and not been to Europe 124. Probabilities: P (traveled to Europe)
