Z=yn
divide both sides by n to get y by itself
Z/n=yn/n
Cross out n and n, divide by n
Then becomes 1*1*y=y
Answer:
y=Z/n
Answer:
Expectation number of books a customer will purchase = 1.3
Step-by-step explanation:
x : 0 1 2
p(x) :0.2, 0.3, and 0.5
Expectation
E(X) = ∑x P(x)
= 0 X 0.2 +1 X 0.3+ 2 X 0.5
= 1.3
Expectation E(X) = 1.3
Expectation number of books a customer will purchase = 1.3
