Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFProbability of 3 students,
P(A) = 1/2, P(A̅) = 1/2
P(B) = 1/3, P(B̅) = 2/3
P(C) = 1/4, P(C̅) = 3/4
So, Probability of no one solve the question is = \(\frac 1 2 \times \frac 2 3 \times \frac 3 4\) = 1/4
⇒ P(None) = 1/4
Then, The probability to solve the question is = 1 - 1/4 = 3/4
Hence, the correct answer is "3/4".
