Question

The probability of certain event is:

• A. $\frac{1}{2}$
• B. $\frac{1}{3}$
• C. $\frac{1}{6}$
• D. $1$

Answer 1

The correct option is D

$1$

The probability of a certain event is always 1 as the number of possible outcomes is always equal to the number of favourable outcomes for a certain event. For example, chances that red ball is chosen from a bag having only red balls, such an event is called a certain event and the probability of a certain event is always 1.
