In this lesson we talk about normal distribution is by using a practical approach – getting you to do the questions while explaining how it works at the same time. We talk about how the bell curve is symmetrical, the area underneath the curve is the probability, and what standard deviation means in relation to …
In this tutorial I teach you guys how to use binomial distrubtion tables as well as culumative binomial distrubtion tables. Make sure you have watched my binomial distribution lessons before watching this video.
In this tutorial we find the probability of X being bigger than or smaller than a certain number. You have to use the formula multiple times and add / subtract probabilities.
In this lesson we talk about how to use the formula nCr*p^r*q^(n-r) to solve binomial distribution problems.
In this lesson i talk about when binomial distribution is used and give you an example of how it works. Next lesson I will talk about using the formula.
In this lesson we explain what expected values are, and give you two examples for working it out.
Probability lesson 4 – Mutually exclusive events in tree diagrams
In this lesson we talk about what independent events are, and do some sample problems with the formula for calculating the probability of independent events occurring, P(A and B) = P(A) x P(B).
In this lesson we talk about how to solve a probability question by drawing a tree and multiplying the probabilities along the tree to get a solution to the problem.
In this lesson we start talking about discrete random variables and discrete probability distributions.
