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?

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 ...

1 out of 1000 births results in fraternal twins; 1 out of 1500 births results in identical twins. Identical twins must be the same sex but the sexes of fraternal twins are independent and we assume each sex the probability is 1/2 ; If there are 5 sets of twin girls, what is the probability that at least four of the sets are identical twins?

Question 3) 1 out of 1000 births results in fraternal twins; 1 out of 1500 births results in identical twins. Identical twins 1 must be the same sex but the sexes of fraternal twins are independent and we assume each sex the probability is 2. Part A. Build the corresponding tree diagram. Part B. If two girls are twins, what is the probability they are fraternal twins? Part C. If there are 5 sets of twin girls, what is the...

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

Compare the results from parts a. and b. Are they equal? Click the icon to view the data table. a. P(subject told the truth | negative test result) = (Round to three decimal places as needed.) b. Find the probability of selecting a subject with a negative test result, given that...

JOSÉ AND JORGE-IDENTICAL TWINS WITHOUT IDENTICAL LIVES José and Jorge were identical twins separated at birth. José grew up in a large family in an impoverished slum in the middle of a crime-ridden and polluted district of a major city. Jorge grew up in an upper-middle class professional family with one other brother in a suburban community in the same city. Despite the fact the José and Jorge were identical twins, their lives and health could not have been more...

3. Two identical balls leave from the same height at position 1 & 2 with the same speed but at different angles. When two balls come back to the same height again (at position 3), what is NOT the same for both balls? A. Acceleration B. Potential energy C. Kinetic energy D. Momentum 1 2 3 4. Two balls of equal mass are thrown horizontally with the same initial velocity. They hit identical stationary boxes resting on a frictionless horizontal...

7.(30 points) Two identical (same mass) charged spheres hang without motion from massless strings of length L at angle θ as shown. The m agnitude of the charges is the same, q, but they have opposite sign. An electric field of magnitude E points in the positive x direction. What is the mass of each sphere? Include a free-body diagram. Make sense of your answer by analyzing limiting cases for two variables in your solution. Teo Eアー hchalge
