Given
Probability distribution table
Find
Mean , variance and Standard Deviation
Step-by-step explanation
As we have given
X = 0 , 1 , 2 , 3 , 4 , 5
P(X) = 0.15 , 0.20 , 0.35 , 0.22 , 0.07 , 0.01
Mean
Formula is given by
first we find the values of X.P(X)
Variance =
standard deviation =
Final Answer
Therefore ,
Mean = 1.89
Variance = 1.38
Standard Deviation = 1.17
