Best ResponseYou've already chosen the best response.0So it's asking for you to find the probability that you will get 3 out of the 5 total questions in the test right, where there are 4 different choices for each.

Best ResponseYou've already chosen the best response.0so would you use 20 since each question has 4 choices?

Best ResponseYou've already chosen the best response.0Let's think of it this way. If the probability of getting the question right is 1/4, and the probability of getting it wrong is 3/4, then essentially you will find your final result to be 1/4 * 1/4 * 1/4 *3/4 *3/4
