What if the events are not equally likely?
Equally likely implies that the all of the outcomes have the same probability of occurring and that the event is fair. If something is not equally likely, then one or more outcomes are more likely to occur than others and the event would be unfair.
What are the examples of equally likely events?
Getting a 3 on the toss of a die and getting a 5 on the toss of a die are equally likely events, since the probabilities of each event are equal. Getting an even number on the toss of a die and getting an odd number on the toss of a die are equally likely events, since the probabilities of each event are equal.
What is an example of a chance experiment?
A chance experiment is something you can do over and over again, and you don’t know what will happen each time. For example, each time you spin the spinner, it could land on red, yellow, blue, or green. An event is a set of one or more outcomes in a chance experiment.
What is the probability of an unlikely event?
A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.
What is an impossible event in probability?
Probability of an impossible event is 0. Impossible event is an event that is non existing. There is no possibility that it can happen. Hence the probability of occurrence is 0.
Which of the following is not an example of equally likely event?
Answer. A bag is full of balls having different colors and sizes. Now pick up a ball randomly from the bag. The probability of all the balls will not be the same.
What is not equally likely?
What probability is considered unlikely?
0 – 10%
Acquisition Risk Management Probability Definitions
| Probability of Occurrence | ||
|---|---|---|
| 0 – 10% | or | Very unlikely to occur |
| 11 – 40% | or | Unlikely to occur |
| 41 – 60% | or | May occur about half of the time |
| 61 – 90% | or | Likely to occur |
When two events have no outcomes in common they are called what?
Events are said to be mutually exclusive (or pairwise disjoint) if no two events have any outcomes in common.
How many different equally likely outcomes are there?
For more than one coin, it will be assumed that for all the coins, heads and tails are equally likely. Throwing a single die can produce six possible outcomes. All six outcomes are assumed equally likely. For any number of dice, the six faces are assumed equally likely to be produced.

What is unlikely happen?
If you say that something is unlikely to happen or unlikely to be true, you believe that it will not happen or that it is not true, although you are not completely sure.
Which event is impossible to happen?
An event E is called an impossible event if P(E) = 0. This happens when no outcome of the experiment is a favourable outcome. For example, in throwing a die, the event of getting a natural number greater than 6 is an impossible event.
Which probability is not possible?
The probability of an impossible event is 0. Because it cannot occur in any situation.
How do you know if outcomes are equally likely?
1. The outcomes in a sample space S are equally likely if each outcome has the same probability of occurring. In general, if outcomes in a sample space S are equally likely, then computing the probability of a single outcome or an event is very straightforward, as the following exercise demonstrates.
