A student appears for tests I, II and III. The student is successful if he passes either in tests I and II or tests I and III. The probabilities of the student passing in tests I, II and III are p, q and \(\frac{1}{2}\) respectively. If the probability that the student is successful, is \(\frac{1}{2} .\) then
- \(p=q=1\)
- \(p=q=\frac{1}{2}\)
- \(p=1, q=0\)
- \(p=1, q=\frac{1}{2}\)
Answer
(B) p=q= 1 2
