05: Students of two different schools have examined the math subject. The number of students of the first school was ( 60 students), while the number of students of the second school was (90 students). The pass rate in the first school is (70% )and in the second school is( 50%). If a student was selected randomly and found to be successful , then what is the probability that this student is from the second school?
