What is the probability that the other child is 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 probability of one boy and one girl?
The probability of having at least one boy and one girl is the probability of any case except either of the two extremes = 1 – 1/16 – 1/16 = 14/16.
What is the probability of getting at least one girl?
The probability of at least one girl is 1−14=34.
Is having 3 daughters lucky?
“Vietnamese tradition says that if you have three girls, you will be lucky for a very long time,” Tran joked Monday as he sat with his wife and two other daughters in a room at Fountain Valley Regional Hospital and Medical Center.
What is the probability of both children being boys?
But we know that one child is a boy, so that means that GG isn’t a possibility. Thus, the sample space is reduced to: BB, BG, GB. Therefore, the probability of both children being boys given that one is a boy is 1/3. P ( 2, 1) = P ( 2). P ( 1) What would be the logic behind this?
What is the probability of having at least one girl child?
Of these 7 have at least one girl in the mix. Thus the chance of having at least one girl is 7/8 = 87.5\%. Originally Answered: If there are 3 children in a family, then what is the probability that there is at most one girl child?
How many possible combinations of 2 boys and a girl?
As we have seen from the other answers, there are 3 permutations out of 8 which contain 2 boys and a girl. But what if we looked at the combinations instead? The combinations of 2 genders among 3 children are: 2 girls, 1 boy can be rearranged, and the boy can have 3 positions (youngest, middle or oldest).
What are the odds of having a baby in each generation?
You can see that the chance of having at least one boy is 1 / 2 in the first generation, 3 / 4 in the second, and 7 / 8 in the third. This generalizes to ( 2 n − 1) / 2 n in the nth generation.
