Question

answer the question.
what is the probability of an impossible event?
(1 point)
○ 0
○ 1
○ -1
○ 0.1

Explanation:

Probability measures the likelihood of an event. An impossible event cannot occur. By definition, the probability of an event \(E\) is \(P(E)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). For an impossible event, the number of favorable outcomes is \(0\). So \(P(E) = \frac{0}{\text{Total number of outcomes}}=0\). Also, probability values range from \(0\) (impossible) to \(1\) (certain). Negative values like \(- 1\) are not valid for probability. And \(0.1\) represents a \(10\%\) chance (a possible but not certain event), while \(1\) represents a certain event.
