I have a question regarding a probability question. If four people are randomly selected what is the probability that at least one is born on my birthday. This would make me think that I want to do the formula of(adsbygoogle = window.adsbygoogle || []).push({});

1 - (1/365)^4 which comes out to be

1 - .000000000005636405776 = .999999999 which just doesn't seem right to me.

I also have to do what is the probability that one is born on my birthday which makes me think that I want to do (1/365)^4

Am I anywhere near the right path?
