Solve it fast and correctly. I will rate accordingly with multiple votes. Need 100% correct answer. There are eight seats at a rectangular table - three on each of the longer sides and one on each of the shorter sides. Six adults and two children sit around the table, with each seating configuration equally likely. What is the probability that the two children will end up seating next to each other on one of the longer sides of the table?
If you flip a coin, there is a 1/2 chance you will receive a heads. If you flip a coin twice, you have to use the product rule to multiply each independent flip to find out what the odds of getting two heads in a row. (1/2 x 1/2=1/4.) By this rule, the odds of flipping a coin 13 times in a row twice and getting the exact same thing both times are 213. Mathematically, what are the chances that any two frog siblings will receive exactly the same complement of chromosomes due to random independent assortment (not counting random genetic recombination) Remember to add together the odds for both egg and sperm. What is this number for a human zygote? What does this tell you about the odds of being identical to one of your siblings, even without taking into account recombination (and not counting identical twins)?

Bonnie and Connie are twins with identical purses. Bonnie needs 35 cents to pay for a parking meter. Suppose that Bonnie's purse has 5 quarters, 3 dimes, and 2 nickels while Connie's purse has 2 quarters, 5 dimes, and 3 nickels in it. Not being able to tell the difference between the purses, Connie picks one at random and grabs two coins from it. What is the probability that Bonnie picked her own purse given that she drew out enough change to pay for her parking meter? (Note: Bonnie needs to put in at least 35 cents to pay her parking meter.)
