A quick quiz consists of 2 multiple choice problems, each of which has 6 answers, only one of which is correct. If you make random guesses on all 2 problems, (a) what is the probability that all 2 of your answers are incorrect?

280

Step-by-step explanation:

Through trial and error, one can figure out that the answer is 280. Now, you might first try to go 8 * 6 * 4, which equals 192. However, if you get the product of two negative numbers, it becomes a positive, which we can use. Using the numbers -7, -5 (which cancel out each other making the product positive), and 8, the product of all of them is 280. The largest product that Khushali can make is 280.

8 * 6 * 4 = 192

(-7) * (-5) * 8 = 35 * 8 = 280
