- A continuous probability distribution differs from a discrete probability distribution in several ways. The probability that a continuous random variable will assume a particular value is zero. As a result, a continuous probability distribution cannot be expressed in tabular form.
- I want to find the discrete distribution of X, where expected value of x, E(X)=3 and the Variance of X is 15. X=1,2,3,4,5,and 6. What is the easiest way to find the distribution of X. I really appr...
- (Discrete) Variance = 2 p x . Standard Deviation = 2 x 2 p x For each value we determine the squared deviation from the mean. We multiply these squared deviations by the probabilities. Sum the results to get the variance. The standard deviation is the square root of the variance. Again, the “divide by how many” is embedded into the relative frequencies. For the credit card example, the
