In a family with 2 children, excluding multiple births, what is the probability of having 2 girls? Assume that a girl is as likely as a boy at each birth. The probability of having 2 girls is (Type a fraction. Simplify your answer.)
2. Suppose that a family is going to keep having children until they have at least one girl. Further suppose we can model successive births as boy and one independent trials with p P(girl) and P(boy) = 1 - p. Let Y denote the total number of children in the family. Compute, for y 2, (i) the probability that the first boy born is the y-th child born; [2] (ii the probability that the first girl born is the y-th...
For every family with 2 children, denote the sex of the first and the second child by a pair xy (where x and y can be either a boy or a girl), and suppose all 4 possible combinations of xy are equally likely.(a) What is the conditional probability that the second child is a girl, given that the first child is a boy. (b) The king comes from a family of two children. What is the probability that his sibling...
A family has three children. Every child was born to be a boy or girl with 50% chance. The probability of this family having at least one boy is?
Four families. One of them has 0 kid; two of them each has one; and the remaining has two kids. The gender is not known. Suppose one family is randomly chosen.Let M denote the number of the boy(s), and F be the number of the girl ( s) (M,F, or both, can be 0.) a) Write out the joint probability distribution of M and F. SHOW THE TABLE b) P(M > 0 ) = ? (c) Write out the marginal...

10. If there are 25 people in a room, what is the probability that at least two people have the same birthday? 11. A family has three children. Find the conditional probability of having two boys and a girl given that the first born is a boy.
What is the probability of a family having 2 girls and 1 boy?
Discrete Math: A couple is planning to have a family. Let us assume that the probability of having a girl is 0.48 and a boy is 0.52, and that the gender of this couple's children are pairwise independent. They want to have at least one girl and at least one boy. At the same time, they know that raising too many kids is difficult. So here's what they plan to do: they'll keep trying to have children until they have...
