Question

if an event has a probability of $\frac{1}{2}$, it is considered:
a. an unlikely event
b. a likely event
c. an impossible event
d. an even chance event

Explanation:

Probability values range from \(0\) (impossible event) to \(1\) (certain event). An event with probability \(\frac{1}{2}\) means there is an equal chance of the event occurring or not occurring.

• Option a: Unlikely events have probability \(P\) where \(0 < P<\frac{1}{2}\).
• Option b: Likely events have probability \(P\) where \(\frac{1}{2}

• Option c: Impossible events have probability \(P = 0\).
• Option d: An event with \(P=\frac{1}{2}\) has an even - chance (equal chance of happening or not happening).

Answer:

d. an even chance event
