front 1 Q1. What is a probability experiment?  back 1 A probability experiment is chance process that leads to well defined outcomes. 
front 2 Q2. Define sample space  back 2 A set of all possible outcomes from a probability experiment. 
front 3 Q3. What is the difference between an outcome and an event?  back 3 An outcome is a result of a single trial from a probability experiment while an event is can consist of more than one outcome. 
front 4 Q4. What are equally likely events?  back 4 Equally likely events have the same probability of occurring. 
front 5 Q5. What is the range of the values of the probability of an event?  back 5 Range of the values 0 to 1 inclusive 
front 6 Q6. When an event is certain to occur, what is its
 back 6 The probability when an event is certain is: 1 
front 7 Q7. If an event cannot happen, what value is assigned to its probability?  back 7 When an event can not happen, the value is assigned is: 0 
front 8 Q8. What is the sum of the probabilities of all the outcomes in a sample space?  back 8 The sum of all the outcomes in a sample space is: 1 
front 9 Q9. If the probability that it will rain tomorrow is 0.20, what is the probability that it won’t rain tomorrow? Would you recommend taking an umbrella?  back 9 The probability that it won't rain tomorrow is 0.80. The probability that it won't rain is 0.80 more than the probability that it will rain  0.2, so an umbrella won't be needed. Although it would be nice to have one in your car just in case  just saying. 
front 10 Q10. Define mutually exclusive events.  back 10 If they cannot occur at the same time. (I.E. They have no outcomes in common).
