Mathematics
My Scando-Germanic friend, Odd Zahlen, often brings a die to class to answer multiple-choice final exam questions. Each multiple-choice question on this particular examination consists of three choices, and Odd decides to pick answer (a) if a 1 or 2 appears on a roll of the die, to pick (b) if a 3 or 4 appears on the die, or to pick (c) if a 5 or 6 appears. Assume that the correct answers are uniformly distributed among the choices (a), (b), and (c). What is the probability of obtaining exactly 5 correct answers on a ten question examination using this method?

Step-by-step explanation:
From each multiple-choice question, there consists three answers to each;
So the probability of picking, the correct answer as they are uniformly distributed among the choices (a), (b), and (c) will be;
P(correct answer) =![\frac{1}{3}](/tpl/images/0508/2662/5506e.png)
Now, to determine the probability of obtaining exactly 5 correct answers on a ten question examination using this method
Let use A as representative for the numbers of correct answers out of 10 questions that is being answered.
∴
