Three molecules of type A, three of type B, three of type C, and three of type D are to be linked together to form a chain molecule. One such chain molecule is ABCDABCDABCD,and another is BCDDAAABDBCC. a. How many such chain molecules are there? [ Hint: If the three A's were distinguishable from one another- A1 A2, A3-and the Bs, Cs, and Vs were also, how many molecules would there be? How is this number reduced when the subscripts are removed from the A's?] b. Suppose a chain molecule of the type described is randomly ·what is the probability that all three molecules of each type end up next to one another (such as in BBBAAADDDCCC)?
