In a hospital, 13 boys were born in succession before a girl was born. What is the probability that after 13 male births, the 14th child will be a boy?
The probability of birth of a girl child or a boy child is 50% or 0.5 in each time of birth as it is controlled by the Sex chromosomes.
The sex chromosomes are segregatted into gametes according to Mendel's law of segregation. The eggs always contain X chromosome and sperms may have either X or Y chromosome , Hence the probability of the fusion of a X chromosome bearing egg with Y chromosome of sperm is 50% and the probability of the fusion of a X chromosome bearing egg with a sperm having X chromosome is 50% irrespective of the succession of birth. So the the probability of 14th child wiil be a boy is 50% or 0.5.

Ignoring twins and other multiple births, assume babies born at a hospital are independent events with the probability that a baby is a boy and the probability that a baby is a girl both equal to 0.5. If the first 5 children born are girls, what is the probability the next born child is a boy?

The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 4058 grams and a variance of 163,216. If a newborn baby boy born at the local hospital is randomly selected, find the probability that the weight will be less than 4744 grams. Round your answer to four decimal places.
The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 3901 grams and a variance of 101.761 if a newborn baby boy born at the local hospital is randomly selected, find the probability that the weight will be between 3582 and 4443 grams. Round your answer to four decimal places.
Assume that the probability of a boy being born is the same as the probability of a girl being born.(a) Find the probability that for family with four children, the two oldest children are girls.(b) Find the probability that for family with four children, exactly two of the children are boys.(c) Find the probability that for family with four children, at least two of the children are boys.
Suppose there were 4,065,014 births in a given year. Of those births, 2,081,287 were boys and 1,983,727 were girls. If we randomly select two women from the population who then become pregnant, what is the probability both children will be boys? If we randomly select two women from the population who then become pregnant, what is the probability that at least one child is a boy?
A couple is planning on having three children. You may assume that one child is born at a time (no twins or triplets), that each child was born two years apart from one another, and that it is equally likely for the couple to have a boy or a girl. Construct a tree diagram and show the sample space. a) What is the probability that the oldest child is a girl and the two younger children are boys? b) What...
