What is the probability that the other child is also a boy?
Since about half of the births are male, the probability of the second child being a boy is . 50. f) If B1 = first child is a boy, B2 that the second is a boy, then, by the independence rule and the formula for conditional probabilities, p(B2 | B1) = p(B2) = . 50.
What is the chance of having one boy and one girl?
The odds of having a girl or a boy are the same with a one in two chance of it being one or the other. 50/50 if you like.
How many are the possible outcomes of having two boys?
There are 8 possible outcomes, all equally likely (if we assume each gender is equally likely).
How do you find the probability of odds?
To convert odds to probability, take the player’s chance of winning, use it as the numerator and divide by the total number of chances, both winning and losing. For example, if the odds are 4 to 1, the probability equals 1 / (1 + 4) = 1/5 or 20\%.
What is the probability of a family with two girls?
In a family with 2 children there are four possibilities: Since we are given that at least one child is a girl there are three possibilities: bg, gb, or gg. Out of those three possibilities the only one with two girls is gg. Hence the probability is 1 3.
What are the chances the other child is a girl?
Information about the child. The chance the other child is a girl is 1 2. This is a very different procedure from ( 1) picking a two-child family at random from all families with two children, at least one a boy, born on a Tuesday. The chance the family consists of a boy and a girl is 14 27, about 0.52.
What is the boy or Girl paradox in probability?
Boy or Girl paradox. The Boy or Girl paradox surrounds a set of questions in probability theory which are also known as The Two Child Problem, Mr. Smith’s Children and the Mrs. Smith Problem.
How many children are selected from a family with two children?
From all families with two children, at least one of whom is a boy, a family is chosen at random. This would yield the answer of 1 3. From all families with two children, one child is selected at random, and the sex of that child is specified to be a boy. This would yield an answer of 1 2.
