如何在Angular中计算出数组的概率？

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `
    <div>
      <h1>数组概率计算</h1>
      <p>原始数组: {{ originalArray }}</p>
      <p>概率结果: {{ probabilityArray }}</p>
    </div>
  `,
})
export class AppComponent {
  originalArray: number[] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
  probabilityArray: number[] = [];

  constructor() {
    this.calculateProbability();
  }

  calculateProbability() {
    const frequencyMap = new Map<number, number>();
    const totalLength = this.originalArray.length;

    // 计算每个元素出现的次数
    this.originalArray.forEach((num) => {
      frequencyMap.set(num, (frequencyMap.get(num) || 0) + 1);
    });

    // 计算每个元素的概率
    frequencyMap.forEach((count, num) => {
      const probability = count / totalLength;
      this.probabilityArray.push(probability);
    });
  }
}
