# How to make probability distribution table

Probability tables can also represent a discrete variable with only a few possible values or a continuous variable that’s been grouped into class intervals. A probability table is

## Discrete Random Variables & Probability Distribution Functions

Calculate the mean and standard deviation of the probability distribution. Solution: Mean (x̄) is calculated using the formula given below x̄ = ∑ [xi * P (xi)] Mean (x̄) = 2 * 0.22 + 3 * 0.48 + 4 * 0.25 + 5 * 0.05 Mean (x̄) = 3.13 Standard
