What is the median of 4 and 7?
For a dataset with an even number of values you take the mean of the two center values. So if the dataset has the values 1 4 7 9 the two center values are 4 and 7. The mean of these middle values is (4 + 7) / 2 = 5.5 so the median is 5.5.
How do I find my nCx?
Formula: nCx = n! / (n – x)!
In other words you calculate the factorial for n and then divide that by the product of the factorials for n-x and x. This gives you the number of combinations or the number of ways of getting x successes in n trials of a binomial.
How do you do nPr and nCr on a calculator?
How do you calculate nCr and nPr?
In Maths nPr and nCr are the probability functions that represent permutations and combinations. The formula to find nPr and nCr is: nPr = n!/(n-r)! nCr = n!/[r!
