Biology Lab-Dice Probability 

Hypothesis: We want to see what the probability is of rolling two regulation, 6 sided dice. We want to find out what combination will come up the most, we both believe it will be seven.

Controlled Variable: Each die has 6 sides, and we will be using 2 dice.

Manipulated Variable: Throwing of the dice.

Responding Variable: The combination of each roll of the 2 dice.

Procedure: 1. We will roll 2 dice 100 times

                   2. Then we will record the combination of each roll.

1. And then calculate the recorded numbers, and find what comes up the most.

Conclusion: The purpose of this experiment was to find the probability of rolling two dice. We set up a controlled experiment where we rolled two 6-sided dice 100 times. Our results from our experiment show that 8 was the most common number that came up, it has the 2nd most combinations of the numbers of the 2 dice. These results refuted our hypothesis because we said it would be 7, which has the highest probability since it has the most available combinations. Our experiment has no sources of error, you can't really go wrong with rolling dice.
