Answer:
Conditional probability of a student, who has actually plagiarized, answering "yes" to the survey is 0.375.
Explanation:
This is easily explanined if we first take the probability of each answer (yes / no) depending on what they fet flipping the coin.
- Tails [always yes] = 0.5 -> Plagiarism = 0.5
- Heads [yes or no] = 0.5 > Two option: (1) True Plagiarism = 0.3; (2) False Pagiarism = 0.7
Now, what we have to do is multiply the "yes" answers from both possible coin tosses (0.5 x 0.3) and divide them by the rest of probable answers (0.5, 0.5, 0.5 & 0.3).
Better expressed like this:
0. 5 x 0.3 / 0.3x0.5+0.5x0.5 = 0.375
