A) the number of ways an outcome may occur divided by the total number of possible outcomes
B) the total number of possible outcomes minus the number of ways a particular outcome may occur
C) the likelihood of rejecting the null hypothesis
D) the number of ways an outcome may occur

Null Hypothesis

Probability
