Answer:
A.
Step-by-step explanation:
let me know if you want an explanation :))
This is an example of "classical probability". Whenever the probability of all events is the same, then the probability is calculated by dividing the number of "favorable events" of total events.
For this problem, the total number of events is the total number of balls, it is 40. The number of favorable events it the number of pink balls, it is 6.
So, the answer is 6/40, which can be written as 3/20.
90 % sure
The image attached shows an operation that can be represented with whole numbers, becuase there are positive and negative characters.
So, we know by given that there are +4 circles and -7 circles, and the whole can be expressed as the algebraic sum of them,
Therefore, the model can be represented by the number -3, which is the whole because is the result of the operation that represent each type of element.
