JEE Main 2022 Mathematics question
Let , , be three mutually exclusive events such that + 3p)/6, − p)/8 and − p)/2. If the maximum and minimum values of p are and , then is equal to :
Answer: (2)
Solution
Each probability lies in [0, 1]: (2 + 3p)/6 [0, 1] gives p [−2/3, 4/3]; (2 − p)/8 [0, 1] gives p [−6, 2]; (1 − p)/2 [0, 1] gives p [−1, 1]. For
