According to the general equation for conditional probability if p(anb)=3/7 and p(b)=7/8 what is p(a i b)

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
