Calculating Conditional Probability

Andrea is a very good student. The probability that she studies and passes her mathematics test is 17/20. If the probability that Andrea studies is 15/16 , find the probability that Andrea passes her mathematics test, given that she has studied.

The probability that Janice smokes is 3/10. The probability that she Smokes and develops lung cancer is 4/15. Find the probability that Janice develops lung cancer, given that she smokes.

Exit Ticket The achievement gap in our country refers to students from low-income families not receiving the education they need to break the cycle of poverty. The probability of being considered low-income in the United States is 70%. The probability of graduating college is 33%. The probability of being a low-income student and graduating college is 5. 6%. 1. Calculate the probability of graduating college GIVEN you are a low income student. 2. Calculate the probability that you graduate college OR are low-income. 3. Using ONE of the statistics you were given or calculated, identify one lurking variable that causes low-income students to have low graduation rates. How does that lurking variable relate to low-income and how does it impact student success?
