【When drawing lots,the faster the better?】

《We can see it well if drawing the illustration of the probability.》

Both of the two situation never happens at the same time. When the one happens,the other one never does. If adding the two probability,it's three-tenths. As a result the probability that the latter draws the prize is three-tenths,though to my sorrow I'm not sure why it is. I can understand until its halfway.

In short the probability that both of the former and the latter draw the prize is three-tenths. It seems that when drawing the lots,the faster the better,but it turns out to be superstition. In general the theory can stand up in every situation,but there is one thing to which we paid attention.

When calculating the probability of the lots,it's equal as long as we look over the whole lots. After some people drew the lots and thinking over the probability later,the probability changes from the former one.

As for the former instance,after the former draws the prize…
