a. In CSE230, there were 2 assignments this semester. The probability that you would NOT get above average marks in the first and the second assignments are 0.3 and 0.4 respectively. But if someone does NOT get the above average marks in the first assignment, the probability of NOT getting above average marks in the second assignment becomes 0.6. What is the probability of NOT getting above average marks in both the assignments? b. In Covid-19 pandemic, one out of every 500 people of Dhaka city were affected during this month. If a person is affected with the virus, the test reports are 75% of the time positive, and 4% time if the person is not affected (This 4% is called false positive). Find the probability that the person has virus given that they have been tested positive.
