i feel like it’s B because like... 2 friends have a higher chance. if the coin happens to land on tail, marg and anita can go again for another coin flip.. while sasha has a one time only chance to win. and if the coin happens to land on heads, well sasha automatically wins and the other two loses. the other options are all 50/50 with everyone. everyone has an equal chance of getting picked. apologies if this is wrong though but i’m confident it’s B
