In probability theory, the birthday problem, or birthday paradox[1] pertains to the probability that in a set of randomly chosen people some pair of them will have the same birthday. In a group of 10 randomly chosen people, there is an 11.7% chance. In a group of at least 23 randomly chosen people, there is more than 50% probability that some pair of them will both have been born on the same day. For 57 or more people, the probability is more than 99%, and it reaches 100% when the number of people reaches 367 (there are a maximum of 366 possible birthdays). The mathematics behind this problem leads to a well-known cryptographic attack called the birthday attack. See Wikipedia for more: http://en.wikipedia.org/wiki/Birthday_paradox
About 1 In 1000 Unless you have twins
1 out of 365 These odds improve if she has sex and gets pregnant about 3 months after her birthday.
not very likely
I believe the chances of having the same birthday as one of your parents is: 1 out of 183 and the chances of having the same birthday as both parents is: 1 out of 133,225
There is no simple answer since the times of conception may not be independent events.

1 in 20,000! I know 4 people with my same birthday, 3 of them not being related...
I don't know what the exact odds are but it does happen: My Mum and her older sister are born on the same day 3 years apart, add to the statistical odds of fun I was also born on the same day. Save don't very likely

Odds deal with sets of numbers. You haven't given a group to work with. For example, the odds of two people having the same birthday approaches certainty with a group of thirty or more, but finding someone with your birthday would require 180, just to give a fifty/fifty chance.
Believe it or not it happens very often for example three generations of women in my family have the same birthday i am the third generation I've seen it a lot more too so the odds are high. I agree, I am born on my mother's birthday and in school I had several friends who were also born on their mother's birthdays.
The odds of having sextuplets are 1 in 3,939,040,643.
well it might be that every other generation has twins, and your not in the generation but your kids will be twins because YOUR generation was skipped
