Need help with a math problem

[vortish]

Find a Boolean product of the Boolean variables x, y, and z, or their complements, that has the value 1 if and only if x=1,y=1, and z=1.

a) _
x y z

b _
x y z

c _ _ _
x y z

d _ _
x y z

e
x y z

What's the question here?

Isn't the Boolean product of x, y, and z, where each variable is 1, always going to be 1???

How is this a question? Maybe I'm having a brain fart, but I don't understand what they're asking.

 

[vortish]

yea RHD some of the question for this worksheet are friging stupid because the dont make any sense

 

[ARG]

I don't understand it either. Can you take a picture of the question? Some data may be getting lost when it gets typed up.

 

[Sigurthr]

Ditto RHD's reply. If they're all true then any operations will always result as true.

 

[vortish]

well i done this question to my best so I am just going to leave it for now

 

[rhd]

Oh, I get it. It's (e)

The only one that has each variable as-is, no line above it indicating a complement.

Stupid question. Barely a question.

Where did this come up?

my descrete math homework

here is another one of the work sheet questions

Consider an algorithm that uses only assignment statements that replaces the quintuple (v, w, x, y, z) with (w, x, y, z, v). What is the minimum number of assignment statements needed?
