Answer:
D) 89.6 %
Average or mean of the given data = 89.6 %
Step-by-step explanation:
<em><u>Step(i):-</u></em>
Given data
X : 82 100 84
P(X=x) : 0.40 0.40 0.20
<u><em>Step(ii)</em></u>
Let 'X' be the discrete distribution
Mean of the discrete distribution = ∑ x P( x=x)
= 82 ×0.40 +100 ×0.40 +84 ×0.20
= 89.6
<u><em>Final answer:-</em></u>
Average of the given data = 89.6 %
