A statistics professor has found that a student who studies 90 minutes each day has a probability of .9 of getting a grade of C or better, while a student who does not regularly study 90 minutes each day has a probability of .2 of getting a C or better. It is known that 70% of the students are following this recommendation. Find the probability that, if a student has earned a C or better, that they have followed the professor's study recommendation (to 3 decimal places).
