Answer 5

125 of B's flights were on time. B had 200 total flights. Thus 75 B flights were late.

175 total flights were late. 75 of those were B's late flights, so 100 were A's late flights.

A had 600 total flights, and now we know that 100 were late, so 500 were on time.

I'd make a table, using those numbers and two columns for A or B, two rows for Late or On Time.

Then you can get all the probabilities from the table.
