A student appears for tests \( I, I I \) and \( I I I \). The student is successful if he passes either in test \( I \) and \( I I \) or tests \( I \) and III. The probabilities of the student passing in tests \( I, I I \) and \( I I I \) are \( p, q \) and \( 1 / 2 \) respectively. If the probability that the student is successful is \( 1 / 2 \), thenhttps://bit.ly/YTAI_PWAP https://www.pw.live
