TASK:You have to design boolean circuit (to draw it) which will allow driver to start car engine(car have only two seats).You can start engine and go if:
  1. Key must be in place
  2. Driver must be on seat
  3. He have to be tied
  4. The seet of one passenger is empty
  5. If seat is full passenger must be tied
You have to create table(fill it with 0 or 1), to create function according to table and minimize function.
Finnaly you have to draw all circuits.

(Only hint j have is taht you will have two circuits one will have 4 input values and another will have 2 input values)
Please help :)

Fairly basic "and/or" function, just wondering how much study you have done.

It's easy for me also but then the op would learn nothing.

Apart from the usual table method etc.
You can solve it "verbally" :

conditions 1 to 4:
"Key" AND "Driver" AND "driver-Tied" AND "pass-empty"

condition 5:
"pass-full" AND "pass-tied"

If at least one of the above 2 sentences is satisfied the total condition is satisfied.
That means "OR" between them.
take note that "pass_full" is the negation of "pass-empty"

Combine all in a single sentence and you have the solution.
