Hello, I have the following 2 x 3 contingency table, 1 2 3 Case 12 13 15 Control 10 5 10 I want to find min(x1,x2,x3) P(X=x) where P(X=x) = ( (22 Choose x1) * (18 Choose x2) * (25 Choose x3) ) / (62 Choose 40) If I have 100 such 2 x 3 tables can I find this probability for each table in R? Anyone has an idea of the R code for this? -- Thanks, Jim. [[alternative HTML version deleted]]
