Lesson: The Mean and Standard Deviation of a Binomial Distribution Mathematics
In this lesson, we will learn how to calculate the mean and standard deviation of a binomial random variable.
In a binomial experiment, the probability of a success in each trial is 0.6. If 25 trials are performed, what is the median?
In a binomial experiment, the probability of success in each trial is 0.2 and 40 trials are performed. Let be the random variable which counts the number of successes. Find the variance of .
A binomial experiment has been set up to measure the number of successes, , of trials, where the probability of success in each trial is . State the expected number of successes.
