An eight-sided number cube numbered \(1-8\) is rolled. Find the probability of each outcome. \(P(0 \text { or greater than } 6\) )

Express each fraction as a percent. $$\frac{3}{8}$$

Suppose your cell phone uses a 4-digit personal identification number (PIN) to lock it from use. Use probability to explain how someone is unlikely to guess your PIN.

Suppose you play a game where each player rolls two number cubes and records the sum. The first player chooses whether to win with an even or an odd sum. Should the player choose even or odd? Explain your reasoning.
