When rolling a die there are six possible outcomes: rolling a one, two, three, four, five or rolling a six. When rolling for a one, there is one chance out of six to get a one. When rolling for a two, again there is one chance out of six to get a two. The same follows for each of the numbers on the face of a die. Jennifer listed the outcomes in a chart and the probability of each outcome based on six total possible outcomes.

| 3) Now test the theory against actual tosses. Toss the die 60 times. Click here to print out the chart and keep a tally of the actual outcomes. Write the final tally as a fraction over 60. Reduce when possible. Answer Questions #3 through #11. State each of the events and the tally and fraction.
