If you have 10 questions to be asked in an exam : 5 from biology and 5 from chemistry. Each module has 10 lectures. What is the probability that a particular lecture will be asked in the exam ?
- 2 Modules : Chemistry, Biology
- 10 lectures each module
- 10 questions in Exam, 5 from each lecture of each module
- What are the chances for each lecture that might be asked in the exam ?
For example, what is the chance that one of the 10 lectures from Biology will make it to the 5 questions asked in the exam ?
Would like a simple walkthrough to the solution. This is not homework, just thought of it and cannot get it right.
I said 1/5 * 10 = 2 .. does that mean 20% chance ? I can't be sure.
