Step-by-step explanation:
To find the given probaility we need the formula for the probability of any given event. This is given below;
![Pr(Event)=\frac{number\text{ of favorable outcomes}}{\text{Total number of possible outcomes }}](https://img.qammunity.org/2023/formulas/mathematics/college/3fybi2t4blujwy48n92k5hvmsl9jl3ezz6.png)
Considering this, the number of favorable outcomes refers to the number of times we can get
21,15,11 and 9. In 35 sided dice, their appearance can only occur once. Therefore, the number of favorable outcomes is 4.
Next, the total number of possible outcomes is all the numbers that can occur when the dice is rolled. This is 35
Workings
Therefore, we can have the probability of one of the numbers occurring as;
![\text{Probability}=(4)/(35)=0.1143](https://img.qammunity.org/2023/formulas/mathematics/college/830cj0k0it1wdy42es5p8v80f8crrgj8vu.png)
