Step-by-step explanation:
- In this test the probability has to be found that the first test was passed and the students were able to clear the second test already
- So for conditional probability we get P (M/N) = P(M and N) / P(N)
- So P(first / second) = P(first and second) / P(first)
- = 0.25 / 0.45
- = 0.55
- So percentage will be 0.55 x 100 = 55%
