I've been stuck trying to simplify this Karnaugh map for hours, I always keep getting a simplification which doesn't work in the truth table.
Simplifications I've tried so far but aren't correct according to the truth table:
F = A + !B * !C + B * !C
F = A + !B + C
F = A + !B * !C + B
F = A + B + !C
F = A * !B * !C + !B * !C + B * !C
F = A + !A * !B * !C + !A * B * !C

Is this right for your map?
>>269362
>>269335
>>269367
A + (!B*!C + B*!C)
A + (!B + B)*!C
A + 1*!C
F(A,B,C) = A + !C
Try this.
>>269369
did it work?
>>269369
>>269371
A + 1*!C did not work, unfortunately.
It goes wrong at row 1 in the truth table, which is
001 = 1
and since A = 0 and !C is 0, all the slots are left as zero so it becomes 0*0*0 = 1 which is false.
There could be something that I'm missing here myself, but according to a site I tried to brainlessly solve it with the correct answer is:
F = !B + C

Ah, linked the wrong one:

You had the variables in the map shuffled I think.
If I use this map I get the right answer.

Oh yeah, it does work using that map. Thanks a ton, anon.
