Lesson: Dependent and Independent Events Mathematics
In this lesson, we will learn how to calculate probabilities for dependent and independent events and how to check if two events are independent.
A bag contains 7 blue marbles and 42 red marbles. A marble is drawn from the bag, recorded, and then replaced. Another marble is then drawn. What is the probability that the first marble is blue and the second is red?
In an experiment a coin is flipped and a die rolled once, then the upper face of each is observed. is the event that the coin lands heads side up and the die lands with a prime number showing. is the event that the die lands with an even number showing. Find the probability of the occurrence of event and not .
A bag contains 18 white balls and 9 black balls. If 2 balls are drawn consecutively without replacement, what is the probability that the second ball is black and the first one is white?
