If you randomly meet three people on the beach, what is the probability that AT LEAST ONE of them speaks English?
The first person probability that speaks english: 36/60 = 0.6
The second person probability that speaks english: 35/59 = 0.593220339
The third person probability that speaks english: 34/58 = 0.5862068966
Probaility of at leat one of this three happening = 0.2086 ==> 20.9%
Second answer:
Probability that AT LEAST ONE of them speaks English is 20.9%
