What is the probability of a couple having 3 daughters in a row?

There is hence a 1 in 2 chance (50% or 0,5 probability) of either a boy or a girl on each occasion. Therefore, by the multiplication principle, the probability of having 3 girls in a row is 12×12×12=18 .

What is the probability of having 4 sons in a row?

What is the probability that in a family of 3 children there will be at least one boy?

question_answer Answers(3) The probability that each child will be a boy is 1/2. The probability that each child will be a girl is 1/2. The probability of at least 1 boy = 1 – the probability of no boys. boys which = 3/8 + 3/8 + 1/8 = 7/8.

What is the probability of a family having a girl?

Data from the US and Scandinavia show that the true figure is more like 51% for a boy and 49% for a girl. In addition statistics show that the probability of the child having a specific sex is correlated with the sex of the previous children.

3/8
This is a Binomial Distribution Problem. There are 4C2 ways to have exactly 2 boys & 2 girls, in any order, so this gives 6/16 =3/8 as the correct probability. if you have 4 children these are the possibilities…

What are the chances of having a fourth girl?

	All same sex	Different sexes
4 children	12.5% all girls or all boys	37.5% 1B/3G or 1G/3B
5 children	6.25% all boys or all girls	25% BBBB/G or GGGG/B
6 children	3.125% all boys or all girls	12.5% BBBBB/G or GGGGG/B

What is the probability that if a couple has four children?

As a result a family of 4 children, with 1 girl is 4 times more likely than a family of four with no girls. We will ignore the slight imbalance of boys over girls at birth, and call it 50/50. There are 2^4, or 16 equally likely outcomes for a family of 4 children.

What is the probability of 1 or 3 girls?

Therefore the odds of 1 OR 3 girls must be .5 because 1 girl and 3 girls each has a .25 probability. If the probability of (1 OR 3 girls) equals .5, then the probability of 2 girls must be a different number. The probability of 2 or more girls, is the sum of the probability of 4 girls (.06125) (—-.5 to the 4th power—— ),

What is the probability of five female births in a row?

There are two ways (Boy (B) or Girl (G) to fill each slot. So, there are 2 x 2 x 2 x 2 x 2 (2 raised to the 5th power) = 32 sequences of 5 children. As we already know that only one of them is all female, the probability of five female births in a row when all births are independent and p (B) = p (G) = 0.5 is p (G,G,G,G,G) = 1/32 = 0.03125.

What are the odds of having a girl out of 4 boys?

The five possible outcomes for girls are 0,1,2,3,4. The odds of 1 girl out of 4 is .25 and the odds of 1 boy out of 4 is .25 (same as the odds of 3 out of 4 girls).
