N individual m baskets each round each one can choose M basket in the probability of throwing a ball in the throw is p to find the number of balls in all baskets after the K-wheel valueThe expected number of balls based on the full expectation formula is dp[1]*1+dp[2]*2+...+dp[n]*n as WWhere Dp[i] is the probability of a person throwing in dp[i] = C (n, i) *p^i* (1-p) ^ (n-i) The final answer is W*k#include

The difference between throwing an exception using throw and throw ex in C, Generally, we use try/catch/finally statement blocks to catch exceptions, as we mentioned here. What is the difference between throw and throw ex when an exception is thrown? Assume that several methods are called as follows: → Call the Method1 method in the Main method. try/catch exceptions.→ Call the Method2 method in the Method1 method. try/catch exceptions.→ Intentio

Throwing Dice LightOJ-1064Method:Set ANS[I][J] Indicates the probability that I have a dice point that is exactly J. Then ans[1][1] to ans[1][6] are 1/6.Apparently, $ans [i][j]=sum\{ans[i-1][j-k]\} (1The upper limit of N and X is very small, directly processing the result of all the points exactly a certain value, and then do again like the prefix and things to deal with all points greater than or equal to a value of the result. Here the answer needs
