Which probability method involves estimating a probability by using personal judgment or an educated guess?

Subjective probability

Step-by-step explanation:

Subjective probability is the probability method which comes directly from a person's judgment or expertise regarding a certain topic related to the possible outcomes. This method is called "subjective" because it does not use any sort of formal calculation and is based solely on guesses based on knowledge and experience.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
