Questions: The probability of the event is 0.125 . (Type an integer or decimal rounded to three decimal places as needed.) Can the event be considered unusual? A. No, because the probability is greater than 0.05 . B. No, because the probability is 0.10 or less. C. Yes, because the probability is 0.05 or less. D. Yes, because the probability is greater than 0.10 .

Solution Steps

To determine if an event is considered unusual, we typically compare its probability to a threshold value, often 0.05. If the probability is less than or equal to 0.05, the event is considered unusual.

1. Compare the given probability (0.125) to the threshold (0.05).
2. Determine if the probability is greater than or less than or equal to 0.05.
3. Based on the comparison, select the appropriate answer.

We are given the probability of an event as \(0.125\). The threshold to determine if an event is unusual is \(0.05\).

We need to compare the given probability \(0.125\) to the threshold \(0.05\).

An event is considered unusual if its probability is less than or equal to \(0.05\). Since \(0.125 > 0.05\), the event is not considered unusual.
