Two liquids, neither of which mixes with water, are spilled onto water, forming thin films on the water surface. When the films becomes much thinner than the wavelength of light as they spread, you observe that one film becomes dark and the other bright in reflected light. The film that is dark has an index of refraction (a) Higher than that of water . (b) Lower than that of water . (c) Equal to that of water. (d) Lower than that of the bright film. Justify your answer.

4.3 Binomial Coefficient The first part of the binomial probability formula consists of a fraction called the binomial coefficent. It uses the factorial notation with 3 values: 1.) Number of trials n 2.) Number of successes k 3.) Number of failures (n - k) The binomial coefficient formula is \frac{n!}{(k!)(n-k)!} Notice the number of trials is in the numerator and the successes/failures are in the denominator. Example: Calculate 10 choose 4. This translates as 10 trials with 4 successes. That means the number of failures is equal to 6 since the total successes + failures. Also $(n-k) = (10 - 4) = 6$. The binomial coefficient is $\frac{10!}{(4!)(6!)} = \frac{10 \cdot 9 \cdot 8 \cdot 7 \cdot 6 \cdot 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1}{(4 \cdot 3 \cdot 2 \cdot 1)(6 \cdot 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1)} = \frac{10 \cdot 9 \cdot 8 \cdot 7}{(4 \cdot 3 \cdot 2 \cdot 1)} = \frac{5040}{24} = 210$ (To make the calculations easier, try to cancel as many values as possible) Calculate 18 choose 6 This means 18 trials with 6 successess
