When discussing accomplishments in activities that involve chance, such as shooting baskets in basketball, the expected success rate is a crucial concept. Simply put, it represents the percentage of attempts that are expected to be successful under normal conditions. In the given exercise, a professional basketball player typically makes 80% of his shot attempts. This figure, the expected success rate, serves as a benchmark against which any specific series of shot attempts can be compared.

Understanding the expected success rate helps in predicting performance over the long term. The rate results from examining historical data which, in this example, is the player's past performance indicating that 8 out of 10 shots, on average, go in. It is the starting point for making informed guesses about future outcomes and serves as a standard for evaluating actual game results. Higher variability is seen in small sample sizes; therefore, the expected success rate is more accurate when applied to larger number of attempts.

At the heart of predicting outcomes in games of chance, probability plays a central role. Probability is a measure of the likelihood that a particular event will occur. Measured on a scale from 0 to 1, where 0 indicates impossibility and 1 indicates certainty, probability quantifies uncertainty.

In this scenario, the probability of the basketball player making a basket on any given shot is 0.8, or 80%, reflecting the expected success rate. Calculating the probability of an event involves considering all possible outcomes. For instance, when the player shoots the ball, there are two outcomes: the shot goes in, or it doesn't. With a consistent success rate of 80%, the probability tells us that over many attempts, the player should make roughly 80 out of every 100 shots. This likelihood helps in understanding the potential for deviations or the player having a 'bad' night, especially when related to the number of shots taken, which ties to the idea of statistical convergence.

Statistical convergence is essential when it comes to understanding the behavior of probabilities over the long term. This concept is encapsulated in the Law of Large Numbers, which states that as you increase the number of trials or attempts (like basket shots), the average of the results tends to get closer to the expected value.

In more straightforward terms, the more shots the basketball player takes, the more likely his success rate for that game will hover around the 80% mark. If he were to take an infinite number of shots, we would expect the success rate to be exactly 80%. On nights when the player takes only a few shots, the small sample size allows for greater fluctuations that don't necessarily reflect his typical abilities. This results in a higher likelihood of deviation from the expected success rate, leading to what might be considered a 'bad' night. Therefore, the Law of Large Numbers is a reassuring principle that with enough attempts, randomness will even out, and skill or expected rates will shine through.
