October 5th is the most common birthday. (thats my birthday!) May 29 is the least common. i hope that answered your question. :l
It is difficult to know exactly how many people have October birthdays, but it is one of the most common months, with October 5th and 6th being the most popular birth dates of Americans.
Millions around the world.
Let us assume that there are exactly 365 days in a year and that birthdays are uniformly randomly distributed across those days. First, what is the probability that 2 randomly selected people have different birthdays? The second person's birthday can be any day except the first person's, so the probability is 364/365. What is the probability that 3 people will all have different birthdays? We already know that there is a 364/365 chance that the first two will have different birthdays. The third person must have a birthday that is different from the first two: the probability of this happening is 363/365. We need to multiply the probabilities since the events are independent; the answer for 3 people is thus 364/365 × 363/365. You should now be able to solve it for 4 people.
obviosly, they celebrate birthdays but they do it with a lot of alchocol!
They both have two birthdays.
Cake! It is a common tradition to have cake on birthdays, and "cake" rhymes with "luck."
They don't. They only celebrate 15th birthdays, which is a quinceanera.
There are many such cultural practices :- Marriage Celebration of Birthdays Shopping for Festivals Praying before meals
It is to celebrate the day of your birth. and the reason why peoples 18th birthday is so important is because they are growing into an adult.
cumpleaños diferentes
Only those people with birthdays.
Prob(two sets of matched birthdays) = 1 - [Prob(No matched birthdays)] + [Prob(One set of matched birthdays)] = 0.63
