Question
Transcribed Image Text:1) A lunch special at the local diner comes with a choice of beverage, choice of
sandwich, and choice of side. There are 4 different beverages, 7 different sandwiches,
and 3 different sides. Two of the sandwiches can be ordered toasted or cold. The other
five are always served cold. How many different choices are there for a lunch special?
a. 4+ (2.2+5) +3
b. 4+ (2.2+7)+3
c. 4.(2.2+5) 3
d. 4 (2.2+7).3
2) f is a 3-to-1 correspondence from the domain A to a target set B.
Given this information, which sets could possibly be A and B?
a. A = {a, b, c, d, e, f} and B = {0, 1}
b. A = {a, b, c, d, e, f} and B = {0, 1, 2}
c. A = {a, b, c, d, e, f} and B = {0, 1, 2, 3}
d. A = {a, b, c, d, e, f} and B = {0, 1, 2, 3, 4, 5}
3) f is a function that maps 4-bit binary strings to the set {a}. For x € (0,1}4, f(x) = a.
Which property best describes the function f?
a. Bijection
b. 2-to-1 correspondence
c. 4-to-1 correspondence
d. 16-to-1 correspondence
