Answer:
Well it depends on many things, How high u toss the coin, what angle u catch it at, the many times that it spun while it was in the air, and if she decides the timing, as in if she's going to catch the coin, or let it fall in her hand. I'd say the coin will land on heads, thing is I kinda can't explain it without it sounding like a crazy or dumb explanation lol. if u want me to explain it with my theory, let me know
