Videos and lessons to help High School students learn how to
develop a probability distribution for a random variable defined
for a sample space in which theoretical probabilities can be
calculated; find the expected value.
For example, find the theoretical probability distribution for
the number of correct answers obtained by guessing on all five
questions of a multiple-choice test where each question has four
choices, and find the expected grade under various grading
schemes.
Common Core: HSS-MD.A.3, HSS-MD.A.4
Constructing probability distribution for random variable.Try out our new and fun Fraction Concoction Game.
Add and subtract fractions to make exciting fraction concoctions following a recipe. There are four levels of difficulty: Easy, medium, hard and insane. Practice the basics of fraction addition and subtraction or challenge yourself with the insane level.
