Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y-----> size of the sample space
if a die is rolled the sample space is
if two dice rolled the sample space is
so
The possible pairs are
The size of the event space x is
substitute
Simplify
