When a particular type of thumbtack is​ dropped, 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 times with the following​ results: point​ up: ​48 times; point​ down: 52 times. a. What is the experimental probability that a particular type of thumbtack will land point​ up?

b. What is the experimental probability that a particular type of thumbtack will land point​ down?

c. If the experiment was tried another 100 times would the same results​ occur? Why?

d. Is it expected that nearly the same results occur on a second​ trial? Why?​
