Assuming a 1:1 birth ratio, the laws of probability predict that half the children in a family will be boys and half will be girls. a) What is the probability that this expected outcome would occur in a family of four children? Show your work. (2 points) b) What is the probability that something other than the expected outcome would occur in a family of four children? Show your work. (2 points) c) What is the probability that the third child will be a boy? Show your work. (1 point)

Step 1
- The expected outcome is having half boys and half girls in a family of four children. - The total number of possible outcomes for a family of four children is 2^4 = 16. - The number of ways to have 2 boys and 2 girls in a family of four children is given by the Show more…

Assuming a 1:1 birth ratio, the laws of probability predict that half the children in a family will be boys and half will be girls. a) What is the probability that this expected outcome would occur in a family of four children? b) What is the probability that the second child will be a girl? c) What is the probability that the family has children in following order: boy, boy, girl, girl?

Find the probability that in a family of 4 children will be (a) at least 1 boy, (b) at least 1 boy and 1 girl. Assume that the probability of a male birth is 1 2 .

1) A family with 4 children. Suppose that when a child is born, there is a 50% chance that the newborn will be a female. a. Determine the probabilities associated with the number of daughters in the household by calculating the probability distribution. b. What is the probability that a family has at least three daughters?
