5. Exam A – Problem 1 A = R1 + [(RBU) x (1 - R1)]
= .9850
B = R2 =.95
C = R1 + [(RBU) x (1 - R1)]
= [(.80) x ( )]
= .9320

6. Exam A – Problem 1
RS = A x B x C
= x .95 x .9960
= .9320

7. Exam B – Problem 1 A = R1 + [(RBU) x (1 - R1)]
= .99
B = R2 =.92
C = R1 + [(RBU) x (1 - R1)]
= [(.88) x ( )]
= .988

8. Exam B – Problem 1
RS = A x B x C
= .99 x .92 x .988
= .8998
