Random number generation has many practical applications in various fields. Here are some examples: Cryptography: Random number generation is a crucial component of cryptographic systems. Cryptographic protocols rely on random numbers to create secure encryption keys, nonces, and other critical components of the system. Games: Random number generation is used extensively in computer games to create unpredictable outcomes, which makes the gameplay more exciting and challenging. Simulation: Random numbers are used in simulations to generate random events, which helps to model complex systems and predict their behavior.
Tip is typically calculated as a percentage of the total bill amount that is paid to a service worker such as a server, bartender, or hairdresser, as a way to show appreciation for their service. The exact percentage of the tip can vary depending on the country, region, and service industry, but it is usually between 15% and 20% of the total bill. To calculate the tip amount, you multiply the total bill amount by the tip percentage as a decimal.
