Identical twins come from a single egg that split into two​ embryos, and fraternal twins are from separate fertilized eggs.​ Also, identical twins must be of the same sex and the sexes are equally​ likely, and sexes of fraternal twins are equally likely. If a pregnant woman is told that she will give birth to fraternal​ twins, what is the probability that she will have one child of each​ sex? Use the data table below to find the probability.

boy/boy   boy/girl   girl/boy   girl/girl
Identical_Twins   1   0   0   1
Fraternal_Twins   10   10   10   10

Answer #1

total number of  fraternal​ twins = 10+10+10+10 = 40

total no. of   fraternal​ twins with one child of each​ sex = 10+10 = 20

required probability = 20/40 = 0.50

    Identical twins come from the same egg and hence are of the same sex. Fraternal twins have a 50-50 chance of being the same sex. Among twins the probability of a fraternal set is 13 and an identical set is 23 . If the next set of twins are of the same sex, what is the probability they are identical?

    2) Identical twins come from the same egg and hence are of the same sex. Fraternal twins have a 50-50 chance of being the same sex. Among twins the probability of a fraternal set is p and an identical set is q=l-p. If the next sets of twins are of the same sex, what is the probability they are identical?(10p)

    Problem 7. (Graded, 10 points) Assume that identical twins are always of the same sex, equally likely boys or girls. Assume that for fraternal twins, the firstborn is equally likely to be a boy or a girl, and so is the secondborn, independently of the first. Assume that proportion p of twins are identical, and q = 1-p of twins are fraternal. Find formulae in terms of p for the following probabilities: a) P(both boys) b) P(firstborn boy and secondborn...

    According to the American Medical Association, one-third of all twins are identical, and the other two-thirds are fraternal. All identical twins are (obviously) same-sex, but the sex of fraternal twins is determined independently, as with other, non-twin siblings. Assuming that male and female children are equally likely, what is the probability that a randomly chosen set of same-sex twins is identical? a. 0.75 b. 0.6667 c. 0.25 d. 0.3333 e. 0.5
