It's the kind of question that students are frequently asked to calculate by hand in introductory statistics classes, and going through that exercise is a good way to become familiar with the mathematical formulas the underlie probability (and hence, all of statistics). But let's be honest: w...
A permutation calculates the number of outcomes where order of events matters, but not all outcomes are equally probable or favorable. Learn how to calculate the probability of permutations using functions and factorials. Probability A probability is the likelihood of an event occurring. When ...

Find the mean of the probability density function f(x) = \frac {x}{6} for 0 \leq x \leq 4. a) Given the following density function calculate the respective cumulative density function. f(x) = \begin {cases} 0 & x 0 \\ x^2+ \frac{4}{3} & 0 x 1 \\ 0 & x 1 \end ...
Calculate the probability of the single random event Identify the event with mutually exclusive outcomes –Whenever you have to calculate probability, either the event should occur or shouldn’t. There should always be one condition as two things cannot take place at the same time. For Example –...
Calculate the probability of the second event occurring. The probability of rolling a "2" is still 0.167. By comparison, the probability of rolling an even number is three in six, or 0.5, since there are three even numbers on the six faces. Step 3 Continue this process until you have c...
A confidence interval, in statistics, refers to the probability that a population parameter will fall between two set values.
Consider, for example, that you want to look at a small dataset such as the possibility of rolling a six when you roll a single die. If on the first roll, you roll a 2, on the second a 5, and on the third a 4, the empirical probability is 0/3=0%. The empirical probability i...
