If 15 strangers are all in a room what is the probability of them all having the same birthday?
To determine the probability of 15 random people all having the same birthday, consider each person one at a time. (This is for the non leap-year case.)The probability of any person having any birthday is 365 in 365, or 1.The probability of any other person having that same birthday is 1 in 365, or 0.00274.The probability, then, of 15 random people having the same birthday is the product of these probabilities, or 0.0027414 times 1, or 1.34x10-36.Note: This answer assumes also that the distribution of birthdays for a large group of people in uniformly random over the 365 days of the year. That is probably not actually true. There are several non-random points of conception, some of which are spring, Valentine's day, and Christmas, depending of culture and religion. That makes the point of birth, nine months later, also be non-uniform, so that can skew the results.

How many baby girls does china abort per year?
The one child policy was established in the 1970's in order to control a rapidly growing Chinese population. This resulted in heavy discrimination and violence against girls and women. Because Chinese culture prizes male children as the continuum of family bloodlines, a custom of killing baby girls through either infanticide or abortion became increasingly common. The development of ultrasounds, that allow the sex of an unborn child to be determined have promoted instances of sex-selective abortion, where a fetus is aborted if it happens to be female. This has caused a wide gap in the gender ratio of Chinese people. The current statistic is 119 males to every 100 females.
