It is known that 70% of men support a certain law. The probability that the coin lands on heads between 2 and 4 times is 0.78125. To answer this question, we can use the following formula in Excel: (5, 0.5, 2, 4) What is the probability that the coin lands on heads between 2 and 4 times?

The following examples illustrate how to solve binomial probability questions using : EXAMPLE 1ĭebra flips a fair coin 5 times. The syntax for is as follows:ī(trials, probability_s, number_s, number_s2)

The function finds the probability of getting a certain number of successes in a certain range, based on a certain number of trials where the probability of success on each trial is fixed. So, to find the probability that the coin lands on heads more than 3 times, we simply use 1 – BINOM.DIST(3, 5, 0.5, TRUE). Note: In this example, BINOM.DIST(3, 5, 0.5, TRUE) returns the probability that the coin lands on heads 3 times or fewer. The probability that the coin lands on heads more than 3 times is 0.1875. To answer this question, we can use the following formula in Excel: 1 – BINOM.DIST(3, 5, 0.5, TRUE) What is the probability that the coin lands on heads more than 3 times? The probability that the coin lands on heads 2 times or fewer is 0.5. To answer this question, we can use the following formula in Excel: BINOM.DIST(2, 5, 0.5, TRUE) What is the probability that the coin lands on heads 2 times or fewer? The probability that Nathan makes exactly 10 free throw attempts out of 12 is 0.063852.

To answer this question, we can use the following formula in Excel: BINOM.DIST(10, 12, 0.6, FALSE)

If he shoots 12 free throws, what is the probability that he makes exactly 10? Nathan makes 60% of his free-throw attempts. The following examples illustrate how to solve binomial probability questions using BINOM.DIST: Example 1 probability_s_cumulative: TRUE returns the cumulative probability FALSE returns the exact probability.probability_s: probability of success on each trial.The function BINOM.DIST finds the probability of getting a certain number of successes in a certain number of trials where the probability of success on each trial is fixed.īINOM.DIST(number_s, trials, probability_s_cumulative) This tutorial explains how to use the following functions in Excel to solve questions about binomial probabilities: The binomial distribution is one of the most commonly used distributions in statistics.
