Need help with a probability question about my grades
I just completed a test and got 47/50.
I was COMPLETELY sure of 43 of those questions. I switched my answers for only 4 questions. What are the odds that me switching my right answer into a wrong answer?
For context, these questions were a,b or c questions so technically its a 1 in 3 chance always, but I'm curious if me switching my answer could have gotten me closer to 50/50, or maybe i should changed all 7 questions that I was not sure about.
