Final answer:
The probability in question typically involves finding the area of the shaded part divided by the total area, but since no dimensions were provided, the question is unanswerable. Probability calculations for continuous variables use the area under a curve.
Step-by-step explanation:
The probability that a randomly selected point within the square falls in the red shaded circle can be calculated by finding the ratio of the area of the circle to the area of the square. Unfortunately, the question doesn't provide specific dimensions for the square or the circle. However, to address a different element shared in the question, to calculate probability that x is between two values, we look at the entire distribution shown by a graph or formula and find the area under the curve (or within the rectangle, if it's a uniform distribution) between those two values.
Furthermore, it's important to understand that for a continuous random variable, the probability of it taking on any single value is zero. What we calculate instead is the probability that the variable falls between a range of values, which is represented by the area under the probability distribution curve for that range.
