Consider a binomial experiment with 16 trials and probability 0.35 of success on a single trial.
(a) Use the binomial distribution to find the probability of exactly 10 successes. (Round your answer to three decimal places.)
(b) Use the normal distribution to approximate the probability of exactly 10 successes. (Round your answer to four decimal places.)
These results are almost exactly the same.

Binomial probability is one of those subjects that we learn during high school studies, yet good binomial probability examples are not mentioned in most cases, which doesn’t help to solve various questions or find the answers without turning to formulas that do not fit. It’s all about being able to calculate the probability as binomial probability problems can be compared to purchasing a lottery ticket where one can either win or leave without any luck. Addressing the lack of examples, we provide binomial questions and explain how certain answers have been found to address this or that binomial probability equation.
