When a particular type of thumbtack isdropped, it will land point up (A flat-top thumbtack resting on its flat top
) or point down (A flat-top thumbtack resting on the edge of its flat top and the tip of its needle
). This experiment was repeated 100 times with the followingresults: pointup: 40 times; pointdown: 60 times.
a. What is the experimental probability that a particular type of thumbtack will land pointup?
b. What is the experimental probability that a particular type of thumbtack will land pointdown?
