Given that the Probability of a chance event is a number between zero and one that expresses the likelihood of the event occurring, choose all that are correct.

•0 indicates a certain event
•0.25 indicates an unlikely event
•0.75 indicates a likely event
•1 indicates an impossible event
•0.5 indicates equally likely to occur or not occur.
Please help if you can, thank you! ✨

Answer:

The correct statements are:

• Second statement: 0.25 indicates an unlikely event

• Third statement: 0.75 indicates a likely event

• Last statement: 0.5 indicates equally likely to occur or not occur.

Explanation:

Since the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring, you can translate it into:

  • A zero probability (0) means that the event is impossible, it will never happen. For example, the probability that when you roll a 6-sided die (with numbers 1 to 6) you get an irrational number is 0, meaning that it will never occur.

  • A one probability (1) means that the event will occur with certainty. For instance, the changes to roll an even or odd number when you roll a 6-sided die is 100%

You migth split the likelihood in some notorius outcomes:

  • 0: impossible (the event will never happen)
  • Close to zero (about 0 - 0.3): unlikely (the chances are small)
  • 0.5: even (equal chances of happening and not happening)
  • Close to 1 (about 0.7 - 1): likely (the changes are large)
  • 1: certain (it is 100% sure that the event will happen)

That means that:

  • first statement, 0 indicates a certain event, is incorrect.
  • 0.25 indicates an unlikely event (second statement is correct)
  • 0.75 indicates a likely event (third statement is correct)
  • third statement is incorrect (1 does not indicate an impossible event, but a certain event)
  • 0.5 indicates equally likely to occur or not occur (fith statement is correct).

The correct statements are:

  • 0.25 indicates an unlikely event
  • 0.75 indicates a likely event
  • 0.5 indicates equally likely to occur or not occur.

What are the correct statements?

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

If probability is 0.5, there are equal chances that the event might occur or would not occur. If probability is less than 0,5, it is unlikely the even t would occur and if it is greater than 0.5, it is likely the event would occur.
