is this the correct answer for 'any row' (c(76,41)/c(80,45))*5 - ( (c(76,41)/c（80,45))^5 + (c(76,41)/c（80,45))^4 + (c(76,41)/c（80,45))^3 + (c(76,41)/c（80,45))^2 ) so change of getting a row multiply by 5 = this will give me the chance of geting 1st OR 2nd OR 3th OR 4th OR 5th...

thank you very much. for the rows because i can get 5 different combination (c(76,41)/c（80,45))*5 is that correct? i assume not cause it includes the probability of getting 2 rows together or 3 rows or 4 rows, right?

Hey all, have a problem to solve for my new game game. really appreciate if someone can help me solve this issue: * i need to calculate the probability for a given combination 1. Total number of balls in the box = 80 2. Total number of chosen balls 45 3. for simplicity we have only...
