How to solve binomial probability
WebMar 26, 2016 · To find each of these probabilities, use the binomial table, which has a series of mini-tables inside of it, one for each selected value of n. To find P ( X = 0), where n = 11 and p = 0.4, locate the mini-table for n = 11, find the row for x = 0, and follow across to where it intersects with the column for p = 0.4. This value is 0.004.
