A survey of 850 students conducted in two schools showed the following results:

School A:
*Students who took the bus = 400
* Students who did not take the bus = 150
Total = 550

School B:
*Students who took the bus = 200
* Students who did not take the bus = 100
Total = 300

School C:
*Students who took the bus = 600
* Students who did not take the bus = 250
Total = 850


Calculate the probability that a randomly chosen student from this group of 850 students takes the bus and is from school A.
