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,
[tex]\text{Probability of getting 11}=\dfrac{\text{Favorable outcomes}}{\text{Total number of outcomes}}[/tex]
[tex]\text{Probability of getting 11}=\dfrac{1}{20}[/tex]
[tex]\text{Probability of getting 11}=0.05[/tex]
Therefore, the probability of getting 11 is 0.05.
