An unbiased dice is thrown. What is the probability of getting a number other than 4.
The probability of getting a number other than 4 when an unbiased (fair) six‑sided die is thrown is 5/6.
The die has six faces: 1, 2, 3, 4, 5, and 6. The event “getting a number other than 4” includes the faces 1, 2, 3, 5, and 6, which are five favorable outcomes out of a total of six possible outcomes.
Tip: The probability of an event plus the probability of its complement always equals 1. Here, P(4) = 1/6, so P(not 4) = 1 - 1/6 = 5/6.
