I believe there is a 1/20 chance that Mrs. Galvan will pick a black pin. Since there are 20 pens, each pen has an equal chance of getting picked. For example, you have 2 pens and one of them is blue. The chance of me getting the blue pen is 1/2 or a 50% chance. So your answer will be 1/20 chance.

Step-by-step explanation:
first work out the radius of priya's circle with the equation a =



we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x
this means that if the diameter of dan's circle is 4 times bigger it must be
8x
to find the radius of dan's circle we divide the diameter by to 2 to give
4x 
then use the a=
equation again

which equals 400
hope that helped
