For the first one compute areas of circles of radius 6 and 4. Probability = difference of areas/area of circle of radius 6.
For the second one compute areas of squares of sides 5 and 3, Probability = difference of areas/area of square of side 5.
Dimensions of large rectangle are 6*2 by 3 = 12 by 3.
Dimensions of 3 parallelograms is base = 2, height = 3
Compute area of rectangle and area of 3 identical parallelograms. Probability = areas of 3 parallelograms/area of rectangle
