Two standard dice are rolled, what is the probability of rolling a pair (both the same number)?
2 Answers
The probability of rolling the pair
#P(E)=1/6~~0.17#
Explanation:
We note that, if a die is rolled the sample space:
#S={1,2,3,4,5,6}#
We know that ,if two dice rolled the sample space :
#S={1,2,3,4,5,6}xx{1,2,3,4,5,6}#
i.e. When two dice are tossed together ,
the possible pairs are :
Let ,event
So , the probability of rolling the pair
Explanation:
Since we are rolling two six-sided dice, there are
How many ways can we get double numbers?
We have
Thus, the probability of rolling pairs is
