Two unbiased dice are thrown. Find the probability that the total of the numbers on the dice is greater than 10.
Given:
Two unbiased dice are thrown.To do:
We have to find the probability that the total of the numbers on the dice is greater than 10.
Solution:
Two unbiased dice are thrown.
This implies,
The total number of possible outcomes $n=6\times6=36$.
Outcomes, where the total of the numbers on the dice is greater than 10 (i.e., 11 and 12), are $(5, 6), (6, 5), (6, 6)$
Total number of favourable outcomes $=3$.
We know that,
Probability of an event $=\frac{Number\ of\ favourable\ outcomes}{Total\ number\ of\ possible\ outcomes}$
Therefore,
Probability that the total of the numbers on the dice is greater than 10 $=\frac{3}{36}$
$=\frac{1}{12}$
The probability that the total of the numbers on the dice is greater than 10 is $\frac{1}{12}$.
