My friend and I are sharing a pack of Rolos. When we reach the last one – which both of us want – we decide to flip a coin to see who gets it.
Annoyingly, we only have one coin which we know to be biased: the probability p of getting ‘heads’ satisfies:
- p > 0
- p ≠ 0.5
- p < 1
Can we still use this coin to fairly decide who gets the last Rolo?
