Answer
Mean of this probability distribution = 1.5
Step-by-step explanation
The mean of the probability distribution is called exprecte value and it is given as
E(X) = Σxᵢpᵢ
where
xᵢ = each variable
pᵢ = probability of each variable
We can then calculate.
Mean of this probability distribution
= (0 × 0.3) + (1 × 0.15) + (2 × 0.3) + (3 × 0.25)
= 0 + 0.15 + 0.6 + 0.75
= 1.5
Hope this Helps!!!
