This article aims to determine the category of a given statement and whether the given statement is an example of empirical, classical, or subjective probability. This article uses the concept of three types of probabilities. Classical probability Classical probability can only be used if a finite number of possibilities have the same probability. As such, it isn’t easy to […]

The aim of this question is to find the number of possible ways for which a $5$-card poker hand of a total of $52 $ cards should not have the queen of hearts. In order to solve this problem the right way, we need to understand the concept of Permutation and Combination. In mathematics, the […]

This question aims to find out how many combinations of a set with ten elements could be made. We need to build our understanding of a basic concept of combination for that purpose. Moreover, this question is based on the concepts of statistics. A set is a well-defined collection of different things which may include […]

This article aims to solve a normal random variable X with $ mu = 10$ and $ sigma ^ {2} = 36$. This article uses the normal random variable concept. Like the standard normal distribution, all normal distributions are unimodal and symmetrically distributed with a bell-shaped curve. However, the normal distribution can take any value as its mean and standard deviation. Mean and standard deviation are […]

b( 3, 8, 0.6 ) b( 5, 8, 0.6 ) P( 3 $le$ X $le$ 5 ) when n = 8 and p = 0.6 The aim of this question is to use the binomial random variable and its probability mass function to find probability values. The binomial probability mass function is mathematically defined as: […]
