Each of three football players will attempt to kick a field goal from the 25-yard line. Let \(A_{i}\) denote the event that the field goal is made by player \(i, i=1,2,3 \text {. }\) Assume that \(A_{1}, A_{2}, A_{3}\) are mutually independent and that \(P\left(A_{1}\right)=0.5, P\left(A_{2}\right)=0
