If the success rate of one thing is 1%, what is the probability of success exceeding 1 00 at least once?

If the success rate of one thing is 1%, what is the probability of repeating 100 times at least 1 times? Alternative answers: 10%, 23%, 38%, 63%-the correct answer is 63%. Calculation method: success rate 1%, failure rate 99%, attempts 100 times, total failure probability 99% 100 power, about 37%, at least one success rate 63%. For seemingly impossible things, the success rate will continue to improve in repeated attempts.

This is a wrong mathematical logic. What's the matter? If there is a problem with prescriptions using unrelated events, the standard answer should still be 1%.

Title: If the success rate of one thing is 1%, what is the probability of success at least 1 time after repeated attempts?

Answer: 63%

Detailed explanation: If the success rate is 1%, the failure rate is 99%. According to 100 iterations, the failure rate is 990 power, which is about 37%. Finally, our success rate should be 100%-37%, which is 63%.

There is a famous saying: "If you want to succeed in this world, you must stick to it until you die." In fact, before anyone succeeds, he will encounter many setbacks and even countless failures. If you choose to give up, you will undoubtedly give up a chance of success, because the failure before the vigorous success is often only one step away from success. Since ancient times, those so-called heroes are not luckier than ordinary people, but have more courage to persevere until the end!
