MHT CET · Maths · Probability
In a certain examination, a candidate has to pass in each of the 5 subjects. Hence, the number of ways he can fail is
- A \(5 !\)
- B 5
- C \(2^5-1\)
- D \(2^5\)
Answer & Solution
Correct Answer
(C) \(2^5-1\)
Step-by-step Solution
Detailed explanation
In each subject either he can pass or he can fail Total number of ways \(=2^5\)
Number of ways which he can pass is only Hence, the number of ways in which he can fail \(=2^5-1\)
Number of ways which he can pass is only Hence, the number of ways in which he can fail \(=2^5-1\)
