In this tutorial we talk about how to simplify surds in more detail.
In this introduction to Surds video you learn about what Surds are and how to simplify them.
In this lesson we teach you how to use normal distribution to approximate a binomial distribution and then how to apply continuity correction.
In this lesson I show you how to do normal distribution questions with two types of graphics calculators – TI84+ and TI84+ Silver edition, but the concept should be similar with any graphics calculator.
In this lesson we talk about how to use a table to find the probability that a randomly chosen score in the population will be between two values.
In this lesson we focus on how to calculate z scores using a formula.
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.
