What is the probability that in a family of three children there is one girl?
Originally Answered: In a family of 3 children, what is the probability of having at least one girl? 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\%.
What is the probability of getting 53 Sundays in a leap year?
The probability that a leap year selected at random contains 53 Sunday is (1)7/366 (2)28/183 (3) 1/7 (4) 2/7. We know that a leap year has 366 days. So, we have 52 weeks and 2 days. Hence, a leap year has 52 Sundays.
What is the probability that a three-child family is two girls and one boy?
What is the probability that a three-child family is two girls and one boy? Each possible birth order has P=1/8. That is, P(G,G,B)=P(G,B,G)=P(B,G,G)=1/8. So, P(2G,1B)= 3/8 and P(1G,2B)= 3/8.
How many different three-child families are possible if birth order is taken into account?
There are nothing different three-child families possible if birth order is taken into account.
What is the probability of getting 53 Sundays in 2020?
1 / 7
In 365 days, Number of weeks = 52 weeks and 1 day is remaining. 1 remaining day can be Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday. Total of 7 outcomes, the favourable outcome is 1. ∴ probability of getting 53 Sundays = 1 / 7.
What is the probability of a non leap year having 53 Sundays?
1/7
Answer: The probability of getting 53 Sundays in a non-leap year is 1/7.
What is the probability for a family with three children to have a boy and two girls assuming the probability of having a boy or a girl is equal?
There are 8 possible outcomes, all equally likely (if we assume each gender is equally likely). Hence the choice is 3/8.
What is the likelihood of having 3 girls?
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 . The sex of the 4th child is independent of the sexes of the previous 3 and hence is once again 12 .
What is the probability of having two boys in a family?
, Just interested in math is all. Kinda a hobby. If the family has 3 children, and at most one of the children is a girl, then the probability of having at least two boys is 100 \%. GGG …..
What is the probability of all three children being girls?
The probability of all three children being girls is the same as that as being all boys, 1 8. And so the probability of the children being all boys or all girls is: P (all boys or all girls) = 1 8 + 1 8 = 1 4
How many children can you have with 3 children?
If you have three children and “at most” one would be a girl, then you always have two boys. You may also have another boy as well, but it’s a 100\% chance to have 2. If you meant exactly 2 boys, we just need to find out if we get exactly one girl.
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).
