A binomial model shows that two outcomes have the same probability of occurring. In an experiment with 60 trials to test this model, the researcher found that Outcome A occurred 36 times. How did the experimental outcome compare to the theoretical model?

The result for Outcome A was 6 more than expected.

Outcome B occurred 36% of the time rather than the expected 50%.

Outcome A had an expected probability of 50% but an actual probability of 36%.

The result for Outcome B was 4 less than expected.

1. Well, yes, I expected 30/60 and got 36/60
B happened 60-36 = 24 times. 24/60 = 0.40 or 40% not 36%
The outcome changed, not the probability.
24 is 6 less than expected, not 4
