3. There are 6 white beads and 5 black beads in your pocket. You randomly pull the beads one by one out of your pocket and place them on a table. Let be the probability that the third bead drawn is the first white bead, where a and b are coprime positive integers. What is the value of a + b?

7. A jar contains 6 white beads and 3 black beads. Beads are chosen randomly from the jar one at a time until the third time a black bead turns up. a. Suppose that each bead is replaced before the next is chosen. How many beads should you expect to be chosen in the course of the experiment? [5] b. Suppose that if a bead is white, it is not replaced before the next bead is chosen, but if it...

In this simulation, you sampled the gene pool without replacing beads in the beaker after you drew each one. Thus, f(A) and f(a) in the gene pool changed slightly after each bead was drawn. For example, if you begin with 50 light and 50 dark beads, the probability of drawing a dark bead the first time is 50/100 = 0.500. The beaker would then contain 49 dark beads and 50 light beads, so the probability of drawing a second dark...

5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

MM Review 1 Constants A 0.016 g plastic bead hangs from a lightweight thread. Another bead is fixed in position beneath the point where the thread is tied. If both beads have the same positive charge q, the moveable bead swings out to make the angle θ = 20° and the distance r 11 cm as shown in (Figure 1) Figure < 1of1 9 9 Pat A to solve for the amount of charge on each bead, we must first...

You have a lightweight spring whose unstretched length is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 3.0 g mass from it. This stretches the spring to a length of 5.0 cm . You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length of 4.6 cm...

Problem with data for try #1 Two small beads having positive charges 3q and q are fixed at the opposite ends of a horizontal insulating rod, extending from the origin to the point x-d. As shown in the figure, a third small charged bead is free to slide on the rod. At what position is the third bead in equilibrium? Take q-1.24 HC +3q and d 70.6 cm Defined symbols d length of the rod in m q charge The...

If you go to a crafts store and buy "glitter beads," you get a little plastic tube of tiny, metal covered glass or plastic beads. On a nice dry day, you can get a charge on the beads, and some of them will "hover" in the air inside the tube, maybe 4 mm apart from each other. It's pretty cool. A. To make it even more cool,...

- Vi tal:ros. b The agouti gene determines coat colour in mice. Heterozygous mice have yellow coats, while homozygous dominant mice have black coats. However, having two copies of the recessive alleles is lethal. In a population of 2000 mice, 1082 mice have black coats. Calculate the frequency of each altele.
