1 / Imagine I have 10 balls, one of which is red and nine of which are black. If you pick one of these balls without looking, how likely it is that you will pick the red ball? Question to the interviewer: did the respondent said 1 chance out of 10, 10%?
Circle the correct answer / Yes / No
2 / I will ask you several questions about the chance that certain events are going to happen. I would like you to use this scale that goes from 0 to 100 to indicate the chance that the event occurs. If you chose 0, this means that you are sure that the event will not occur. The higher the number you chose is, the more likely is the event to happen. For example if you answer 50, it means that it is just as likely that the event happens as it does not happen (fifty-fifty). If you indicate a number below 50 it means that the event has more chances to not happen than to happen. If you indicate a number greater than 50 it means that the event has more chances to happen than to not happen. If you answer 100, it means you are certain that the event will occur.
