Dear OP,

Great maths question here (this will be familiar ground to pollsters!): We have a cabin of 35 passengers. Assuming the underlying cabin-light/cabin-dark preferences are evenly distributed amongst the 35 passengers, we then select a sample of 10 passengers from the group - if 100% of our 10 passenger sample prefers cabin-dark, what is the probability that a despite this sample, a majority of the overall group of 35 has a "cabin-light" preference?

Spoiler Alert: it's 0.01%

OP: it's time accept you're in a minority view on this.
