In a multiple choice exam there are 5 questions and 4 choices for each question (a b c d). Nancy has not studied for the exam at all and decides to randomly guess the answers. What is the probability?
The probability of Nancy guessing the correct answer for a single question is ( \frac{1}{4} ) since there are 4 choices (a, b, c, d). For 5 questions, assuming each guess is independent, the probability of guessing all questions correctly is ( \left(\frac{1}{4}\right)^5 = \frac{1}{1024} ). Thus, the probability of Nancy answering all questions correctly by random guessing is ( \frac{1}{1024} ).

What is the proprbility that by guessing at random one can correctly guess the month of a stranger?
There are 12 months in a year, so if you are guessing randomly, the probability of correctly guessing the month of a stranger is 1 out of 12. This can be expressed as a fraction: ( \frac{1}{12} ). In decimal form, this is approximately 0.0833, or 8.33%.
