DESCRIPTION:

Have you ever taken a test and discovered you have no choice but to guess on a couple of problems? In this example problem, we are considering the probability of two independent events occurring.

OVERVIEW:

Test taking probability and independent events | Precalculus | Khan Academy is a free educational video by Khan Academy.It helps students in grades HS practice the following standards HSS.CP.A.2,HSS.MD.A.3,.

This page not only allows students and teachers view Test taking probability and independent events | Precalculus | Khan Academy but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.

1. HSS.CP.A.2 : Understand that two events A and B are independent if the probability of A and Boccurring together is the product of their probabilities, and use this characterization to determine if they are independent..

2. 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..
