Random variables can be any outcomes from some chance process, like how many heads will occur in a series of 20 flips of a coin. We calculate probabilities of random variables and calculate expected value for different types of random variables.

Probability theory began in seventeenth century France when the two great French mathematicians, Blaise Pascal and Pierre de Fermat, corresponded over two problems from games of chance. Problems like those Pascal and Fermat solved continuedto influence such early researchers as Huygens, Bernoulli, and DeMoivre in establishing a mathematical theory of probability. Today, probability theory is a ... What is the probability that the problem is solved?

The closer the probability is to zero, the less likely it is to happen, and the closer the probability is to one, the more likely it is to happen. The total of all the probabilities for an event is equal to one. For example, you know there's a one in two chance of tossing heads on a coin, so the probability is 50%.From this point, you can use your probability tree diagram to draw several conclusions such as: · The probability of getting heads first and tails second is 0.5x0.5 = 0.25. · The probability of getting at least one tails from two consecutive flips is …From this point, you can use your probability tree diagram to draw several conclusions such as: · The probability of getting heads first and tails second is 0.5x0.5 = 0.25. · The probability of getting at least one tails from two consecutive flips is …As we study a few probability problems, I will explain how "replacement" allows the events to be independent of each other. Let's take a look at an example. Example 1 - Probability of Independent Events. Example 1 is pretty easy to comprehend because we are finding the probability of two different events using two different tools. Let's see ...Now divide.
