Brush number of questions: 4
Today learned mathematical knowledge in probability and mathematical expectation, advanced algorithm contest guide 180 to 184
This section feel around to find the probability of an event, find the probability of events, through E (ax + by) = a * E (x) + b * E (y) equation request the desired solution.

CF set up questions then there is a set of https://www.cnblogs.com/2462478392Lee/p/11330547.html
to sum up
I feel a little reading to see the back of mastery, very comfortable feeling, until very difficult subject can not read, then come back a little so mean. Tomorrow you can read all the mathematical knowledge, the next data structures advanced a good school!
