Probability Calculator | Math Calculators Is there a proper earth ground point in this switch box? Write down a single or multiple independent events and the calculator will compute their single or conditional probability, with the steps shown. If there is more than one sample point on a sample space, then this is said to be as a compound event. I've always struggled with algebra and mathematical expressions, especially finding a thorough explanation on how to solve it step by step, i wouldn't have gotten through algebra 1 so easily if it hadn't been for this useful app. For example, suppose we want to know the probability that a z-score will be greater than -1.40 and less than -1.20. Here the set is represented by the 6 values of the dice, written as: Another possible scenario that the calculator above computes is P(A XOR B), shown in the Venn diagram below. Finding P as shown in the above diagram involves standardizing the two desired values to a z-score by subtracting the given mean and dividing by the standard deviation, as well as using a Z-table to find probabilities for Z. Above, along with the calculator, is a diagram of a typical normal distribution curve. In the absence of a parametric assumption, various techniques exist to estimate the density directly (rather than identifying it by estimated parameters as seen above). Note that P(A U B) can also be written as P(A OR B).
