4. Probability Distributions: Practical 4
The Binomial Distribution
Let's go back to the MC-exam example that was described in the theory: You take an exam consisting of #20# MC questions with #4# options each. Unfortunately, you did not study at all and are thus forced to guess the answer to every question. Suppose you need at least #12# correct answers in order to pass the exam.
What is the probability of passing the exam if you were to guess the answer to every question?
Small challenge: to answer this question you can use the function dbinom() as well as pbinom(). Try to find the answer in both ways.
Round your answer to 6 decimal points.
