How to calculate probability

Answer 1

• Choose an event with mutually exclusive outcomes. ...

• Define all possible events and outcomes that can occur. ...

• Divide the number of events by the number of possible outcomes. ...

• Add up all possible event likelihoods to make sure they equal 1. ...

• Represent the probability of an impossible outcome with a 0.

or use the formula :

FAVOURABLE OUTCOMES / TOTAL NO. OF OUTCOMES

Answer 2

To calculate the probability (in terms of percentage):

You need to set up the division.

`(event)/(outcome)` × 100

For example:

What is the probability of rolling a two in a dice.

Now the event here is one since one face of the dice is showing two.

The total number of faces are six. This will be the outcome.

So substitute it to the division.

`(event)/(outcome)` × 100

`(1)/(6)` × 100

0.1666 × 100

Probability = 16.66%
