This formula is derived from the definition of conditional probability and helps in calculating joint probabilities of dependent events.

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

The following two-way table displays data for the 300 graduates who responded to the survey. ... Suppose we choose a random graduate from this data. Are the events "income is $40,000 and …

We are just calculating the probability that they would have a specific trait (that they chose flying as their superpower in Problem 1, or that they were male in Problem 2).

The conditional probability formula is indeed P (A ∣ B) = P (A ∩ B) / P (B), where P (A ∩ B) is the probability of both events A and B occurring together, and P (B) is the probability of event B …

You've experienced probability when you've flipped a coin, rolled some dice, or looked at a weather forecast. Go deeper with your understanding of probability as you learn about …

Here, we'll take a deep dive into the many ways we can calculate the likelihood of different outcomes. From using simulations to the addition and multiplication rules, we'll build a solid …

When it doubt, it's always possible to answer conditional probability questions by Bayes Theorem, it tells us the probability of event A given some new evidence B, though if you forgot it, no …
