Expected winnings in roulette. In the popular casino game of roulette, you can bet on whether the ball will fall in an arc on the wheel colored red, black, or green. You showed (Exercise 3.175, p. 172) that the probability of a red outcome is 18/38, that of a black outcome is 18/38, and that of a green outcome is 2/38. Suppose you make a $5 bet on red. Find your expected net winnings for this single bet. Interpret the result.

In Roulette, a ball spins on a circular wheel that is divided into 38 arcs of equal length, bearing the numbers 00, 0, 1, 2, … , 35, 36. The number of the arc on which the ball stops is the outcome of one play of the game. The numbers are also colored in the manner shown in the following table.

Letter to future nursing students

Write a substantive and heart-felt letter to your future nursing students or practicing nurses if you are planning on being an educator in practice.

In this letter, describe who you were in terms of teaching before you explored the possibilities of technology in education and who you are now, following this experience.

End with sharing with the students what they can expect from their visionary, technologically savvy, and creative teacher! Be sure your letter effectively demonstrates your “techie skills” (color, graphics, links, videos, etc.).
