Question

What's the formula for probability

Answer 1

Answer:

Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.

Answer 2

Step-by-step explanation:

Formula to Calculate Probability

The formula of the probability of an event is:

Probability of an Event Formula

Probability Formula

Or,

P(A) = n(A)/n(S)

Where,

P(A) is the probability of an event “A”

n(A) is the number of favourable outcomes

n(S) is the total number of events in the sample space

Note: Here, the favourable outcome means the outcome of interest.

Sometimes, students get confused about the word “favourable outcome” with “desirable outcome”. In some of the requirements, losing in a certain test or occurrence of an undesirable outcome can be a favourable event for the experiments run.
