Use the sine law: sinB/b = sinA/a
SinB = b*sinA/a
sinB = 3*sin120° /8
∠ B = 18.94° ≈ 19°

Step-by-step explanation:
It would be 50%, because they have a 50/50 chance of getting their seat, even if the first wizard/witch got in the wrong seat.

=21
So, the questions can be wrong are 30-21.
=9 questions..
Thanks!
