What is the probability of your birthday being the same as mine?
The probability of two people's birthday being the same is actually more likely than many would think. The key thing is to note that it doesn't matter what the first person's birthday is. All we need to work out is the probability that the second person has a birthday on any specific day. This probability is 1/365.25 The probability that they were born on June 10th is 1/365.25. The probability that they were born on February 2nd is 1/365.25 and the probability that they were born on the same day as you is 1/365.25
What is the probability of 6 members of one family being born on a different day of the week?
Births are not distributed uniformly over days of the week: there are fewer births at weekends. However, if you do assume that the distribution is uniform, then the probability is 6!/76 = 5040/117649 = 0.0428
What is the probability of being born on the 29th of February?
Fraction:1/1461 Decimal:0.00068446269678302532511978097193703 Percentage:0.068446269678302532511978097193703%
What is the probability of being born in a month with more than 30 days?
Just over 7 out of 12.
What is the probability for family to born 2 boys and a girl?
There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes.However, if you assume that they are independent events then, given that the probability of a boy is approx 0.52, the probability of the other two being boys is 0.4994
