A teacher has two jars of candy on her desk:
Jar 1: Contains 3 Strawberry candies and 2 Orange candies.
Jar 2: Contains 1 Strawberry candy and 4 Orange candies.
The teacher randomly picks two candies from Jar 1 and drops them into Jar 2.
Then, a student reaches into Jar 2 and picks two candies.
What is the probability that the student picks two Strawberry candies?
$\frac{6}{35}$
$\frac{4}{21}$
$\frac{3}{70}$
$\frac{1}{14}$
