Think of "probability" as a scale from impossible to certain. Picture a balance with 'impossible' on one side and 'certain' on the other, and "probability" as the sliding weight in the middle showing how likely something is to happen.

小故事

John was excited about his new garden. He planted sunflowers and watered them every day. However, he noticed some flowers were taller than others. Curious, he asked his neighbor, "Why are some sunflowers taller than others?" His neighbor smiled and said, "There's a probability that each seed has different growth potential. Just like people, no two seeds are exactly alike!"

约翰对他的新花园感到非常兴奋。他种下了向日葵，并且每天都给它们浇水。然而，他注意到有些花比其他的花高。出于好奇，他问他的邻居：“为什么有些向日葵比其他的高呢？”他的邻居微笑着说：“每个种子的生长潜力都有不同的概率。就像人一样，没有两个种子是完全相同的！”
