Recent awards ShuangSeQiu frequent, also spawned another round of lottery fever. Color ball Lottery are very familiar with a lot of kind of lottery, there are a lot of friends come up with a lot of skill, every day to buy a few note, I hope to be able to get in one fell swoop in award. However, like color ball friends, there is no real intention from mathematically thought about your method and the probability of winning the lottery? We want to how to do, in order to more easily in the award it?
Before entering the subject, let's do a little choice.
Suppose now that you have a chance to get astronomical salary in front of you, you have two options, one is to get one hundred million yuan monthly salary, the other is the first day to get a dollar, from the next day, get a day twice monthly salary until the end of the previous, which one do you choose?
Many of my friends a ride eye will be one hundred million figure surprised, one hundred million yuan, unthinkable figures, of course, choose the former. In fact, if you count, you know, which is the real astronomical salary, according to this algorithm, to the end you will get a monthly salary of 1.073 billion yuan of the high price.
To calculate clear result is not difficult, but many times we would be deceived intuition, although the answer is very simple, but if you do not want to step deep or difficult to grasp the truth.
Now let's ask a new question: color ball bag 30 numbers, red ball full in the probability that be?
Color ball a total of only 33 goals, we pack 30 numbers, winning rate should be high, right? A lot of friends to see this value ratio, first think of a very high winning rate, but if we calculate it, you will find, package 30 numbers, red ball the whole probability is only 53%, and to reach more than 60% hit rate, you need to package 31 in order to achieve, including 20 goals, in only 3.5% of the total probability.
This probability is not the will to surprise it?
From this data we can see, the probability of winning is actually very low, because we can not send too much hope that the lottery is a form of entertainment in fact, winning is incidental, is not necessarily reported to the indifferent mood buy in order to receive the best results. But we can also see that the packet number is much greater than the probability of winning the radio, including the 10 numbers, the winning probability is 210 times the radio. Therefore, the appropriate packet number is over the radio to be appropriate.
