We can create the probability distribution for rolling two dice by creating a table to represent the events that make up the sample space.

Explore statistics and probability concepts, including average absolute deviation, with interactive lessons and exercises on Khan Academy.

Practice calculating conditional probability, that is, the probability that one event occurs given that another event has also occurred.

Given a context, create a probability distribution.

In a significance test about a population mean, we first calculate a test statistic based on our sample results. We can then use a table to estimate the p-value based on that test statistic …

The equation P (A and B) = P (A ∣ B) × P (B) might seem confusing at first, but it's essentially saying that the probability of both events A and B happening is the probability of event A …

So, in both questions, “What is the probability that a randomly selected graduate earns under $20,000?” and “What is the probability that a randomly selected graduate earns under $20,000 …
