Question 13 0/1 pts Suppose you have 5 friends, Amy, Bill, Cindy, Dave and Emma. You want to invite them to an end-of semester party, but your room only fits 3 people plus you and your roommate. Bill and Dave aren't talking to each other because Bill borrowed Dave's car and crashed it, and didn't offer to pay the deductible for repairs. So you could invite one or the other, but not both. How would you write this constraint? (Use the first initials of the names to denote the DV that that friend is invited.) B+D = 1: B, D= 1 if invited, 0 if not B+D

Explanation / Answer

Option 3 i.e.

B + D < = 1 B, D = 1 if invited, 0 i not

Summarizes the given constants

since the cases might be

Either B & D both are not invited

or either one of the two is invited

so sum of their presence can be either 1 or 0 but not greater than 1

Hence proved
