Question

Which of the following statements are true for the value of probability of an event ?

• A. An impossible event has a probability equal to '0'
• B. A sure or certain event has a probability equal to '1'
• C. Events that are equally likely to occur have a probability equal to '0.50'
• D. Events that are likely to occur have a probability greater than '0.50'

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A An impossible event has a probability equal to '0'
B A sure or certain event has a probability equal to '1'
C Events that are equally likely to occur have a probability equal to '0.50'
D Events that are likely to occur have a probability greater than '0.50'

For an impossible event, the number of favorable outcomes = 0.

For a sure or certain event, the number of favorable outcomes = the total number of outcomes.

For an equally likely event, the number of favorable outcomes are equal to half of the total number of outcomes.

For events that are likely to occur, the number of favourable outcomes are more than half of the total number of outcomes.
