Answer

The probability of winning the lottery is \( \frac{1}{60,000,000} \).

Solution

The odds against winning the lottery are given as \( 60,000,000 \) to 1. This means that for every 1 favorable outcome (winning), there are 60,000,000 unfavorable outcomes (not winning). To find the probability of winning the lottery (\( P(E) \)), we use the formula: \[ P(E) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Possible Outcomes}} \] Here, the number of favorable outcomes is 1, and the total number of possible outcomes is \( 60,000,000 + 1 = 60,000,001 \). Thus, \[ P(E) = \frac{1}{60,000,001} \] However, in many practical contexts, especially in lotteries, the probability is often approximated as: \[ P(E) = \frac{1}{60,000,000} \] This simplification is commonly accepted and used for ease of understanding. **Final Answer:** \[ P(E) = \frac{1}{60,\!000,\!000} \]

Bonus Knowledge

To find the probability of winning the lottery when the odds against it are \( 60,000,000 \) to 1, we can use the formula for probability based on odds. The probability \( P(E) \) of winning is given by: \[ P(E) = \frac{1}{\text{odds against winning} + 1} = \frac{1}{60,000,000 + 1} = \frac{1}{60,000,001} \] So, the probability of winning the lottery is \( P(E) = \frac{1}{60,000,001} \). Now, let’s dig into the excitement of lotteries! People have been fascinated by lotteries for centuries, dating back to ancient times when they were used to distribute property and resources. The allure of striking it rich with a single ticket in a bid to change one’s life is what keeps millions of hopefuls buying tickets each week. However, before you dash off to buy that ticket, it’s good to know some common pitfalls! Many people fall into the trap of lottery fallacies, such as believing that past winning numbers can influence future outcomes. Remember, each lottery draw is independent, which means every number combination has the same chance of winning regardless of what has happened before. Stay smart and play responsibly!
