In other words, a possible event can have a probability of 0 and still be considered possible, but an impossible event can only have a probability of 0 and cannot be considered possible. If the experimental probability of an event in a random experiment is close to 0, we say that this event is nearly impossible. Does the event, "A hexagon that has a right angle," occur with a probability of zero? P (not e)=0.8 ,the probability of an event cannot be more than 1 . It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. I suspect most people on this site will go for this answer. Probability. An event that occurs for sure is called a Certain event and its probability is 1. If an event is never going to happen then you can describe the probability as impossible. Then the sample space has n elements. We can use words such as certain, likely, evens and impossible to describe the likelihood of events. What is the probability of independent events . An event with a probability of 0.5 will occur half of the time. 1. Probability is 0 for an impossible event Probability is 1 for a certain event Probability is 1 2 for an even chance (for example, getting a head when you toss an unbiased coin) MEP Y7 Practice Book B 137 Example 2 For each event below, mark an estimate of the probability that it will happen on a probability scale.
