The mean of the following probability distribution is:
|
1 $\frac{2}{3}$ $\frac{1}{3}$ 4 |
1 |
We know that mean of probability distribution is → ∑xiP(xi) xi → data point P(xi) → probability of respective data point for given distribution mean (µ) = $0 \times \frac{1}{4}+1 \times \frac{1}{2}+2 \times \frac{1}{4}$ $= 0 + \frac{1}{2} + \frac{1}{2}$ µ = 1 |
