As we study a few probability problems, I will explain how "replacement" allows the events to be independent of each other. If events are independent, then you can easily multiply events together to calculate probability. When you toss a coin, the probability of getting a head is 1 out of 2 or . i.e. So, the total number of outcomes left is 51. I had a very challenging question in class today.
