Article: To return to the Powerball game, you have 5 numbers and a single Powerball. If you guess all 5 of the other numbers correctly but don't get the Powerball, you'll win the second prize. If you calculated your odds of winning the jackpot, you already know that your odds of guessing all 5 numbers correctly are 1 in 11,238,513.  To win the second prize, you would have to guess the Powerball incorrectly. If you calculated your odds of winning the jackpot, you know that your odds of guessing the Powerball correctly are 1 in 26. Therefore, your odds of guessing the Powerball incorrectly are 25 in 26. Use the same equation with these values to determine your odds of winning the second prize: 111,238,513×2526{\displaystyle {\frac {1}{11,238,513}}\times {\frac {25}{26}}}. When you complete this calculation, you'll see that your odds of winning the second prize are 1 in 11,688,053.52. To win other prizes, you guess some, but not all, of the winning numbers correctly. To figure out your odds, use an equation in which "k" represents the numbers you choose correctly, "r" represents the total numbers drawn, and "n" represents the number of unique numbers the numbers will be drawn from. Without numbers, the formula looks like this: r!k!×(r−k)!×(n−r)!((n−r)−(r−k))!×(r−k)!{\displaystyle {\frac {r!}{k!\times (r-k)!}}\times {\frac {(n-r)!}{((n-r)-(r-k))!\times (r-k)!}}}.  For example, you might use the Powerball values to determine your odds of correctly guessing 3 of the 5 chosen numbers from the set of 69 unique numbers. Your equation would look like this: 5!3!×(5−3)!×(69−5)!((69−5)−(5−3))!×(5−3)!{\displaystyle {\frac {5!}{3!\times (5-3)!}}\times {\frac {(69-5)!}{((69-5)-(5-3))!\times (5-3)!}}}  The result of this equation tells you the number of ways that 3 numbers can be chosen correctly out of 5 numbers. Your odds will be that number out of the total number of ways 5 numbers can be chosen correctly. Just as with the base equation, this equation is best solved by typing the entire thing into a calculator or search engine. Some intermediate numbers involved in the calculation would be cumbersome to write down and it would be easy to make a mistake. In the previous example, your odds of guessing 3 of the 5 chosen numbers in Powerball would be 20,160 in 11,238,513. While this formula gives you the odds of guessing only some of the numbers correctly, you still haven't factored in the Powerball. To find your true odds, multiply the result by your odds of getting the Powerball number correct or incorrect (whichever value you want to find).  For example, if you wanted to calculate your odds for getting only 3 of the 5 numbers correct and getting the Powerball incorrect, your equation would be 20,16011,238,513×2526{\displaystyle {\frac {20,160}{11,238,513}}\times {\frac {25}{26}}}, or 1 in 579.76. On the other hand, your odds for getting 3 of the 5 numbers correct and getting the Powerball correct would be 20,16011,238,513×126{\displaystyle {\frac {20,160}{11,238,513}}\times {\frac {1}{26}}}, or 1 in 14,494.11. Once you have the formula down, simply change the value of "k" to find the odds of winning different levels of prizes. Generally, your odds of winning will decrease as the value of "k" increases. If you're calculating odds for Powerball or a similar game, don't forget to multiply your result by the Powerball value.

Article: The best time for a nap is between 12pm and 3pm, at which point your melatonin levels are highest and your energy level tends to be lowest. If you struggle with after-lunch drowsiness, grabbing a few minutes of nap can make you more productive and awake in the long-run, as opposed to gulping down an energy drink and trying to press on. Try to avoid naps after 4pm, especially if you struggle with insomnia. Sleeping too late in the day can make it harder to get to sleep at night, when you want to go to sleep. Grabbing 10-20 minutes of rest is usually best for a middle-of-the-day nap. More than that can leave you feeling drowsier than when you started, meaning you'll have to go through the whole waking-up process for the second time in the day. Alternatively, if you need a serious nap because you slept poorly the previous night, Try to aim for a full REM cycle of 90 minutes. Sleeping for 60 minutes can make you feel groggy for the rest of the day, whereas 90 minutes--a full sleep cycle--can leave you feeling refreshed. The idea of nodding off for too long can keep some people from actually falling asleep. Take the stress off and set an alarm, even if it's only 15 minutes from now, to wake you back up and get you back to whatever you've got to do. You can rest easy knowing you're not going to wake up when it's dark outside. Use your phone to set a quick alarm, or get a coworker to cover for you and knock on your door in 15 minutes. Then return the favor. While it may sound counterintuitive to drink a cup of coffee right before you go to sleep, caffeine's got to travel all the way through your digestive tract before you feel that caffeinated jolt--a process that takes about 20 minutes--so some pro nappers swear by the caffeine nap, which times itself perfectly with your wake-up. Down a quick cup of cold coffee just before nodding off and let the caffeine wake you up sharp and refreshed. It's still a good idea to set an alarm to keep yourself from sleeping too late.
