Ajar contains n − 1 vanilla cookies and one chocolate cookie. you reach into the jar and choose a cookie at random. what is the probability that you will first get the chocolate cookie on the kth try if you (a) eat (b) replace each cookie you select. show that if n is large compared to k then the ratio of the probabilities in (a) and (b) is approximately 1. junghenn, hugo d.. an introduction to financial mathematics (chapman and hall/crc financial mathematics series) (p. 32). crc press. kindle edition.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
