On Friday 25 July, I went to [...], and bought a package containing three paprikas. The green paprika had 2 lobes, the yellow paprika had 3 lobes, and the red paprika had 4 lobes.

What's the probability of getting three distinctly-lobed paprikas in one package?

It might be 6*p*q*r, where:
o = prob(1 lobe) = 0
p = prob(2 lobes)
q = prob(3 lobes)
r = prob(4 lobes)
s = prob(5 lobes) = 0
t = prob(6 lobes) = 0
