there are 5 fictions and 6 non - fictions . how many cases are there such that 2 fictions and 2 non - fictions are selected from them ?
import math
n0 = 5.0
n1 = 6.0
n2 = 2.0
n3 = 2.0
t0 = math.factorial(min(15, int(2.0)))
t1 = n0 * 4.0
t2 = n0 * n1
t3 = t1 * t2
t4 = t0**min(2.0, 5)
answer = t3 / t4
print(answer)
