The following formula from statistics gives the likelihood that a person will arrive within t minutes of \( 3 : 00 \) p.m. \(F ( t ) = 1 - e ^ { - 0.20 t }\). Answer (a) and \( ( b )\) ,(b) Find the likelihood that a person will arrive within \( 5 \) minutes of \( 3 \) p.m. The likelihood that a person will arrive within \( 5 \) minutes of \( 3 \) p.m. is \( \square \% \) .
