WebIn Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.. There are basically two intercepts, x-intercept and y-intercept. WebIf the intercept has a positive sign: then the probability of having the outcome will be > 0.5. If the intercept is equal to zero: then the probability of having the outcome will be exactly 0.5.
