Use mathematical induction to show that P(A1∩A2∩...∩An) = P(A1)P(A2|A1)P(A3|A1∩A2)....P(An|A1∩A2∩...∩ An-1) You can assume that you know P(A|B) = P(A|B)P(B)
Matrix notation:
A=(a1,a2,a3.....,an) = [a1 a2 a3 a4 .....an] are they equal?
look at the sample picture A should be matrix but it uses ( )
rather than [ ]
Given that A is an n×n matrix with the property AX = 0 for all X " 1 A=(a,,a,, 0 0 Let a.) Let e, =| | | ← ith element Comment

(C programming) Given a sequence of numbers a1, a2, a3, ..., an, find the maximum sum of a contiguous subsequence of those numbers. Note that, a subsequence of one element is also a contiquous subsequence. Input The input consists of multiple datasets. Each data set consists of: n a1 a2 . . an You can assume that 1 ≤ n ≤ 5000 and -100000 ≤ ai ≤ 100000. The input end with a line consisting of a single 0. Output...
