Explain why the second result is less.
As the number of trials increases, the probability of getting exactly a specific number of successes that is far from the new mean decreases. For 10 trials with a 50% success rate, 5 is the expected value (mean) and has the highest probability. However, for 20 trials, the expected value is 10, and getting exactly 5 successes is much less likely because the distribution has spread out and centered around a higher value.
