The value that indicates the greatest likelihood that a result occurred by chance alone is .5, which corresponds to a probability of 50%. A p-value of .5 would mean that the results are as likely to occur by chance alone as they are to occur due to the variable being studied. P-values typically range from 0 to 1, and smaller values indicate stronger evidence against the null hypothesis (i.e. that there is no effect or relationship) and in favor of the alternative hypothesis (i.e. that there is an effect or relationship). Therefore, choices A, B, and D all indicate smaller probabilities and thus lower likelihoods of the results occurring by chance alone.
