Two coins are tossed simultaneously. Then, the value of \(E(X)\), where \(X\) denotes the number of heads is
- A \(\frac{1}{2}\)
- B 2
- C 1
- D None of these
Answer & Solution
Correct Answer
(C) 1
Step-by-step Solution
Detailed explanation
Here, \(n=2, \quad p=\frac{1}{2}\)
\(E(X)=\text { mean }=n p=2 \times \frac{1}{2}=1\)
\(E(X)=\text { mean }=n p=2 \times \frac{1}{2}=1\)
