The Statistical Interpretation of a χ² Value Is Determined by Identifying

The statistical interpretation of a χ² value is determined by identifying the P value for each experiment, and the P value is dependent on the number of degrees of freedom (df) in the experiment being examined. For a coin flip experiment, the df value is equal to 1. You perform an experiment to determine how many times out of 100 die rolls that you roll a "1" in a single roll. What would the df value be equal to?

A) 1
B) 2
C) 3
D) 4
E) 5
