A student taking a midterm exam in Ancient History comes to two questions pertaining to a class that he missed, and so he decides to take a random guess on both questions. One question is a true and false question and the other is a multiple choice question with five possible answers. Describe how to calculate the probability to the true/false question.

Sagot :

There's only two outcomes (true or false) and one correct answer.

Therefore, the probability is 1/2 = 0.50 = 50%

Or you could say the odds are 50 50, ie there's a 50% chance of getting it right vs a 50% chance of getting it wrong.
