The probability of selecting a yellow marble from the box is 1 out of 5, or 1/5.
The subject of the question is probability, a topic in Mathematics. The box contains 100 marbles in total (20 yellow, 35 green, 15 blue, and 30 red). The probability of selecting a yellow marble is the number of yellow marbles divided by the total number of marbles. So, the probability is 20 (number of yellow marbles) divided by 100 (total marbles), which simplifies to 1/5. Thus, the probability of selecting a yellow marble is 1 out of 5, or 1/5.

What’s the answer?
the solution for the given equation is x = 30.857.
the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
Given an equation, 6/19=x-12/2x-2
Simplifying this using PEMDAS
cross multiple the equation
12x -12 = 19x -12*19
on the same side
-7x = -228 +12
-7x = -216
x = 216/7
x = 30.857
Therefore, the solution for the given equation is x = 30.857.
