Question 463:



No answer provided yet.

This is an example of the multiplication rule of probability. We need to find out what the probabilty of a correct response is given a random guess for 1 question. Then for each question we simply multiply this by itself.

So if there are three possible answers and only one is correct, the probability of a correct response from random guessing is 1/3  or  .333. The probability of randomly guessing two questions is then .333*.333  = .1108 or about an 11.1% chance.
