Hanukkah runs from Dec 12-20 this year. Imagine today is the 8th and final day of Hanukkah, and you're getting ready to arrange the candles into the holders on the menorah. Traditionally, you place them one at a time from right to left, but today you want to try something different. For example, you could place the first candle in the fifth spot, the second candle in the second spot, the third candle in the seventh spot, and so on. How many different ways are there to pick the candles’ spots?
