The expected value of betting \( \$ 1 \) on one roulette number is approximately \( -\$ .05 \). What does this mean in practical terms? If many people made this bet over the course of the night, the house would expect to take in approximately a \( 5 \% \) return. If I bet \( \$ 1 \) one time, I would expect to leave the table with approximately 95 cents. I am almost guaranteed to lose this bet I am almost guaranteed to win this bet

3. Combinations and Probabilities: 20 pts. You are tasked with creating a code using the following three conditions: 1. The code must consist of exactly 4 characters. 2. Each character can be one of the following: A, B, C, or D. 3. The code can repeat characters, but the first character must be different from the last character.
