Question
Example 5.32
The total revenue from the sale of the three grades of gasoline on a particular day was
Y = 3.0X₁ + 3.2X₂ + 3.4X3, and it was determined that y = 5620 and (assuming independence)
If the X's are ---Select---
distributed, the probability that revenue exceeds 4300 is
p(Y> [
]) = P(Z >
43005620
429.46
= P(Z > -3.07) = 1
- $(1
= 0.9989.
= 429.46.
