Probability Expected Value lesson
Probability Expected Value lesson is a free educational video by TwoMinuteTeacher.It helps students in grades HS practice the following standards HSS.MD.A.3,HSS.MD.B.5,HSS.MD.B.5.A.
1. HSS.MD.A.3 : 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..
2. HSS.MD.B.5 : Weigh the possible outcomes of a decision by assigning probabilities to payoff values and finding expected values.
3. HSS.MD.B.5.A : Find the expected payoff for a game of chance. For example, find the expected winnings from a state lottery ticket or a game at a fast-food restaurant..
