What is the probability that19 rolls of a fair die will show exactly three threes?

answer will be decimal with 4 places

(I wish this could be done with binomial pdf but I couldnt figure out if that was possible.)

C( 19, 3) * (5/6)^16*(1/6)^3 ≈ .2426

Odd, that is what I got aswell but the only answer choices are, .2420, .4840, .0480, .1210 I think I will just go with .2420
