Question

Which of the following is NOT a principle of probability?

A) The probability of any event is between 0 and 1 inclusive.
B) All events are equally likely in any probability procedure.
C) The probability of an event that is certain to occur is 1.
D) The probability of an impossible event is 0.

Answer 1

The principle of probability that is NOT correct is that all events are equally likely in any probability procedure.

Step-by-step explanation:

The principle of probability that is NOT correct is B) All events are equally likely in any probability procedure.

Probability is a number between 0 and 1 (inclusive) that represents the likelihood of an event occurring. The probability of any event is always between 0 and 1, but not all events are equally likely to occur. Some events may have a higher probability than others based on the nature of the situation or experiment.

For example, if we toss a fair coin, the probability of getting heads is 0.5 and the probability of getting tails is also 0.5. These events are equally likely. However, if we pick a card randomly from a standard deck, the probability of getting a spade is 1/4, while the probability of getting a heart is also 1/4. These events are not equally likely.
