Can someone please help me with this problem ?
In Mr. Symons' class, if a person does his homework most days, his chance of passing the course is 90%. On the other hand, if a person does not do his homework most days his chance of passing the course is only 20%.
Mr. Symons claims that 80% of his students do their homework on a regular basis. If a student is chosen at random from Mr Symons 'class, find the following probabilities: A) P (the student passes the course)
B) P the student did homework / the student passes the course C) P (the student passes the course / the student did homework )
