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 ...
Since binomial variable is discrete (numbers), we can use continuous normal distribution to estimate the probability of occurring between 4.5 and 5.5. So, we calculate P(4.5 < X < 5.5) using the normal distribution. After applying the continuity correction, you will then transform the X values...

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...

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: ...
