In a statistics class of 50 students, what is the probability that at least 40 will do their homework on time? Students are selected randomly. This is a binomial problem because there is only a success or a ___, there are a fixed number of trials, and the probability of a success is...
The binomial distribution formula is for any random variable X, given by; P(x:n,p) = nCxx px (1-p)n-x Or P(x:n,p) = nCxx px (q)n-x, where, n is the number of experiments, p is probability of success in a single experiment, q is probability of failure in a single ...
It is important to know whether you have a discrete or continuous variable when selecting a distribution to model your data. The Binomial and Poisson distributions are popular choices for discrete data while the Gaussian and Lognormal are popular choices for continuous data....
2. Binomial Distribution When reports of it include only two alternative possible outcomes, it is construed to mean adiscrete probability distribution. This is most often the case with banking, psychology, and genetics The probability mass function of binomial distributions can be defined in terms of...

What is the mean of the resulting distribution? The critical piece of information that students need here is the mean of a standardized variable is always 0, but that is not obvious from the surface structure of the question. In order to recognize what information is needed to solve this ...
In the given example, the random variable is the ‘number of damaged tube lights selected.’ So let’s denote the event as ‘X.’ Then, the possible values of X are (0,1,2) So, one could calculate the probability by using the formula: ...
Mata has nine new random-variate functions for beta, binomial, chi-squared, gamma, hypergeometric, negative binomial, normal, Poisson, and Student’st:rbeta(),rbinomial(),rchi2(),rgamma(),rhypergeometric(),rnbinomial(),rnormal(),rpoisson(), andrt(), respectively. ...
