You order 10 burritos to go from a Mexican restaurant, 4 with hot peppers, and 6 without. However, the restaurant forgot to label them.

If you pick three burritos at random, find the probability that at least one has hot peppers.

Here's a hint to get you started


P(at least 1 has hot peppers) = 1 - P(none have hot peppers)

I wrote out a tree diagram and it says that there would be a 7/8 probability of getting a burrito where one burrito has at least one with peppers. So that would mean 1/8 would have no peppers?

Well, if you pick 3 burritos and the probability that at least one has hot peppers is 7/8, then the probability that none of the 3 has hot peppers would be 1/8. But I don't think you have calculated the probabilities correctly. What does your tree diagram look like?
