With this information you can go to a Binomial Distribution Table and find the solution. Using the following uniform density curve, answer the question. 43 The Probability Distribution of the Random Variable X, is We know that for any Probability Distribution: sum P(X=x) = 1 Hence; P(X=3)+P(X=4)+P(X=7)+P(X=9 The correct answer is: A bar chart and/or a pie chart. Mean and Variance of Binomial Distribution. 13 5. x is a binomial random variable. In a Binomial Distribution, if 'n' is the number of trials and 'p' is the probability of success, then the mean value is given by ___________. 750. 005 0. 50 9. It means that E (X 13. 73. 2 0. Notice that we cannot use the binomial probability distribution to determine the likelihood of obtaining three successes in 20 trials in Example 1 because the sample size is large relative to the population size. 1 Worksheet key Probability Worksheet Key. 1 Normal Distributions Answers The data gives the following histogram: The data does not appear to be normally distributed but does appear to have a good spread of the data.
