The winning probability is 1/3.
<h3>
What is probability?</h3>
- A probability is a number that represents the likelihood or chance that a specific event will occur.
- Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.
To find the winning probability:
- Favorable outcomes to win are 3 and 6.
- Total outcomes are 6in fair dice.
- To win $20 × 3 or $20 × 6 favorable outcome is 1 (3 and 6 respectively).
- The probability is 1 / 6.
- So, the probability of winning some money = 2/6 = 1/3
Therefore, the winning probability is 1/3.

Answer:
A = 18 units²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h ( b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
By counting squares
h = 3, b₁ = 3, b₂ = 9 , then
A = × 3 × (3 + 9) = 1.5 × 12 = 18 units²
