Title: TED ED Loop Probability
Post by: Jefferson on October 14, 2019, 08:27:25 pm
Hi everyone,
Please help me with the following question. (Video)

I don't really see how the odds of all of them guessing right is 35%.
This would be equivalent of them having a 90.034% of getting their instruments individually.

Also, each musician's action is independent of the others, so how is going about it in a loop more probable than randomly guessing 5/10 boxes for 50%??
