Find probability using frequency distribution

WebTo find the cumulative value for each row, sum the relative frequencies as you work your way down the rows. The first value in the cumulative row equals that row’s relative frequency. For the 2 nd row, add that row’s value to the previous row. In the table, we add 26.1 + 22.7 = 48.8%. WebAn example to find the probability using the Poisson distribution is given below: Example 1: A random variable X has a Poisson distribution with parameter λ such that P (X = 1) = (0.2) P (X = 2). Find P (X = 0). …
