Trang 3Terminal Learning Objective
regulations/course handouts, and awareness of Operational Environment
(OE)/Contemporary Operational Environment (COE) variables and actors
• Define possible outcomes
• Determine cash flow value of each possible outcome
• Assign probabilities to outcomes
Trang 4What is Expected Value?
• Recognizes that cash flows are frequently tied to uncertain outcomes
• Example: It is difficult to plan for cost when different performance scenarios are possible and the cost of each is vastly different
• Expected Value represents a weighted average cash flow of the possible
outcomes
Trang 5Applications for Expected Value
• Deciding what cash flows to use in a Net Present Value calculation when actual cash flows are uncertain
• Reducing multiple uncertain cash flow outcomes to a single dollar value for a
“reality check”
• Example: cost of medical insurance
Trang 6Expected Value Calculation
• Expected Value =
Probability of Outcome1 * Dollar Value of Outcome1
+ Probability of Outcome2 * Dollar Value of Outcome2
+ Probability of Outcome3 * Dollar Value of Outcome3
Trang 7Expected Value Example
• The local youth center is running the following fundraising promotion:
• Donors will roll a pair of dice, with the following outcomes:
• A roll of 2 (snake-eyes): The donor pays $100
• A roll of 12: The donor wins $100
• 3 and 11: The donor pays $50
• All other rolls: The donor pays $25
• Task: You are considering rolling the dice Calculate the expected value of your donation
Trang 8Expected Value Example
• What are the possible outcomes?
• 2, 12, 3, 11 and everything else
• What are the cash flows associated with each outcome?

Trang 18Demonstration Problem
• Sheila is playing Let’s Make a Deal and just won $1000
• She now has two alternative courses of action:
A) Keep the $1000
B) Trade the $1000 for a chance to choose between three curtains:
• Behind one of the three curtains is a brand new car worth $40,000 (which will be taxed at 22.5%)
• Behind each of the other two curtains there is a $100 bill
• Task: Calculate the Expected Value of Sheila’s alternative courses of action
Trang 19Demonstration Problem
• Step 1: Define the outcomes
• Step 2: Define the probabilities of each outcome
• Step 3: Define the cash flows associated with each outcome
• Step 4: Calculate Expected Value
Trang 20Define the Outcomes
Course of Action 1:
• Keep the $1,000
Course of Action 2:
• Trade $1,000 for one of the curtains
• Two possible outcomes:
• New car
Trang 21Define the Probabilities
Keep the $1,000
• Sheila already has the $1,000 in hand
• This is a certain event
• The probability of a certain event is 100%
Trade $1,000 for Curtain:
Car

Trang 25Define the Cash Flows
Keep the $1,000
• Cash flow is $1,000
Trade $1,000 for Curtain
Car $40,000 - $1,000 - $9000 = +$30,000
$100
Value of the car = $40,000 Gives up $1,000 = -$1,000
Trang 26Define the Cash Flows
Keep the $1,000
• Cash flow is $1,000
Trade $1,000 for Curtain
Car $40,000 - $1,000 - $9000 = +$30,000
$100 $100 - $1,000 = -$900

• Your organization has submitted a proposal for a project Probability of
acceptance is 60%
• If proposal is accepted you face two scenarios which are equally likely:
• Scenario A: net increase in cash flows of $75,000
• Scenario B: net increase in cash flows of $10,000
• If proposal is not accepted you will experience no change in cash flows
• Task: Calculate the Expected Value of the proposal

Trang 34Expected Value and Planning
• If you outsource the repair function, total cost will equal $750 per repair
• Historical data suggests the following scenarios:
Trang 35Expected Value and Planning
• Expected Value of outsourcing:
Trang 36Expected Value and Planning
• If you insource the repair function, total cost will equal $65,000 fixed costs plus variable cost of $300 per repair
• How much should you plan to spend for repair cost if you insource?
• Given these assumptions, which option is more attractive?
Trang 37Expected Value and Planning
• Expected Value of insourcing:
• Insourcing is more attractive:
• Total cash flow is higher when repairs are few, but
• Probabilities of more repairs and the savings when repairs are many justify insourcing
100 repairs 25% * (100 * $300) + $65,000 = $95,000 = $23,750
300 repairs 60% * (300 * $300) + $65,000 = $155,000 = $93,000
500 repairs 15% * (500 * $300) + $65,000 = $225,000 = $33,750
