This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Simple probability






2. Sum of consecutive numbers






3. Simple Interest Formula (remember this is the total amount of money in the bank after the interest is earned)






4. The average of 5 numbers is 2. After one number is deleted - the new average is -3. What number was deleted?

13. 1. A and B < A or B 2. A or B > Individual probabilities of A - B 3. P(A and B) = P(A) x P(B) <-- 'fewer options' 4. P(A or B) = P(A) + P(B) <-- 'more options' - Probability of multiple events rules.






14. Odd Factors
