Given:
A 20 sided dice is rolled.
To find:
The probability of getting 11.
Solution:
A 20 sided dice is rolled.
On a 20 sided dice, the possible outputs are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20.
Total number of outcomes = 20
Favorable outcomes or number of 11 = 1
Now,
![\text{Probability of getting 11}=\dfrac{1}{20}](https://tex.z-dn.net/?f=%5Ctext%7BProbability%20of%20getting%2011%7D%3D%5Cdfrac%7B1%7D%7B20%7D)
![\text{Probability of getting 11}=0.05](https://tex.z-dn.net/?f=%5Ctext%7BProbability%20of%20getting%2011%7D%3D0.05)
Therefore, the probability of getting 11 is 0.05.
