A spinner is used on a game board shaped like an isosceles triangle, where the base angles are equal, and it's subdivided into seven regions by drawing altitudes from each vertex to the opposite side and one additional altitude from the apex to the base, splitting one of the base regions into two smaller regions. Three of these regions are shaded. What is the probability that the tip of the spinner will come to rest in a shaded region? Express your answer as a common fraction.
