For example, the odds are 46.3-to-1 that you'll get three of a kind in your poker hand – approximately a 2-percent chance – according to Wolfram Math World. But, the odds are approximately 1.4-to-1 or about 42 percent that you'll get one pair. Probability helps you assess what's at stake and determine how you want to play the game.Which means that when students see fifty percent, they need instead to see it as the decimal value 0.5. In these worksheets, your students will solve word problems that involve calculating percentages. Students will solve real-world problems involving money, stock prices (percent change), discounts, etc. There are 35 worksheets in this set.
