As the number of trials increases in a binomial experiment, calculating probabilities using the previous formula will really drain the batteries in your calculator and possibly even your brain. An easier way to arrive at these probabilities is to use a binomial probability table, which I have conveniently provided in Appendix B of this book. Below is an excerpt from this appendix, with the probabilities from our previous example underlined.

The probability table is organized by values of *n,* the total number of trials. The number of successes, *r,* are the rows of each section, whereas the probability of success, *p,* are the columns. Notice that the sum of each block of probabilities for a particular value of ...
