Given : One dozen students each drop a brass tack six times from a height of six inches onto a level hard surface. They record the number of times the tack lands point up. The table below lists their results.
To Find : the experimental probability that the tack lands point-up for student 4
Solution:
student 4
Point up = 4
non point up = 2
Total = 4 + 2 = 6
Probability that the tack lands point-up for student 4 = 4/6
= 2/3
