Java实现根据概率中奖率

public class ProbabilisticLottery {
    public static void main(String[] args) {
        double probability = 0.1; // 中奖概率为10%
        int totalAttempts = 1000000; // 总共进行1000000次抽奖
        int winningCount = 0; // 记录中奖次数

        for (int i = 0; i < totalAttempts; i++) {
            double random = Math.random(); // 生成0到1之间的随机数

            if (random <= probability) { // 判断是否中奖
                winningCount++;
            }
        }

        double winningRate = (double) winningCount / totalAttempts * 100; // 计算中奖率

        System.out.println("中奖率为：" + winningRate + "%");
    }
}
