If a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct how much credit will you lose for that part of the question?

question with options, you will lose of the credit for that question. Just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing. With five choices, your chance of getting the question wrong is 80% when guessing, and every wrong answer costs you 1/4 of a point. In this case, leave it blank with no penalty. Guessing becomes a much better gamble if you can eliminate even one obviously incorrect response. If you can narrow the choices down to three possibilities by eliminating obvious wrong answers


Using the numbers 1 2 3 5 6 8 0 with no repetition allowed how many 4-digit numbers can be constructed if the number is even?

This is a problem involving combinations. We know we need a 4 digit number. So I'll write 4 blank spaces, to symbolize each digit. ___ ___ ___ ___ The number also has to be even. That means that the last digit must be even. (2, 4, 6, 8, 0) Your list of numbers is 1, 2, 3, 5, 6, 8, 0. How many numbers from this list will work in the last digit place? 2, 6, 8, 0. -- 4 numbers. ___ ___ ___ _4_ For the third digit, any number will work. We have 7 choices. ___ ___ _7_ _4_ for the 2nd digit, the same applies. any number from your list will work. ___ _7_ _7_ _4_ For the first digit, only 6 will work. if you put a 0 in the first digit place, it becomes a 3 digit number. _6_ _7_ _7_ _4_ Now, all we do it multiply these numbers together. 6 * 7 * 7 * 4 = 1176. This means, we can create 1176 unique 4 digit numbers that are even with the list of numbers available. 1000 1002 1006 1008 1010 1012 etc.
