Conditional Probability How to handle Dependent Events Life is full of random events! You need to get a "feel" for them to be a smart and successful person. Independent Events Events can be "Independent"‚ meaning each event is not affected by any other events. Example: Tossing a coin. Each toss of a coin is a perfect isolated thing. What it did in the past will not affect the current toss. The chance is simply 1-in-2‚ or 50%‚ just like ANY toss of the coin. So each toss is an Independent

variable X is a weighted average of the possible values that the random variable can take. Unlike the sample mean of a group of observations‚ which gives each observation equal weight‚ the mean of a random variable weights each outcome xi according to its probability‚ pi. The mean also of a random variable provides the long-run average of the variable‚ or the expected average outcome over many observations.The common symbol for the mean (also known as the expected value of X) is ‚ formally defined by Variance

skills can be used anytime and anywhere. For instance‚ the mathematical usage of probability can aid people in smart decision making‚ and can help people understand their odds. Statistically‚ probability refers to the relative possibility that an event will occur‚ as expressed by the ratio of the number of actual occurrences to the total number of possible occurrences (SOURCE). A rather obvious activity where probability applies is to is gambling. Casino games‚ such as Texas Hold Em’‚ can be played
