2912 is the population . when 12% is increase of the Ann's population

90 degrees converted to radians is pi/2 or π/2 radians.
All socks together: 13
Black socks: 3
Probability to pick out black socks: 3/13
After one pick out (You picked out a pair of black socks):
Probability to pick out black socks: 2/12
Multiply them:
2/12 * 3/13 = 1/26 ≈ 0,038
