Conditional probability problem

#1
Hey all,

I hope you can help me with this problem.

Say that tomorrow I can go to Berlim with a probability of 20%, Madrid with a probability of 10% or New York with a probability of 5% (or stay home with prob of 65%). Then, what is the probability that tomorrow I go to one of those cities knowing that I can only go to one of them.

hi,
you mean, knowing that you went to a city, what is the probability that you picked that particular one right?

I guess, by the definition of the conditional probability it should be the P(city|you travelled) = P(city)/P(travel) so for example P(Berlin) = 0.2/0.35 and so on.
