Explanation:

Step1: Recall probability range

Probability of an event \(P(E)\) satisfies \(0\leq P(E)\leq1\). An unlikely event has \(0 < P(E)<0.5\).

Step2: Analyze each option

• For \(\frac{1}{8}=0.125\), since \(0 < 0.125<0.5\), it represents an unlikely event.
• \(\frac{97}{50} = 1.94>1\), not a valid probability.
• \(\frac{89}{100}=0.89>0.5\), represents a likely event.
• \(0\) represents an impossible event.

Answer:

\(\frac{1}{8}\)
