planters plntrs 6 consonants out of 8 letters
P that the first one is a consonant is 6/8
P that the second one is a consonant is 5/7
P that the 3rd one is a consonant is 4/6
p(all 3 are consonants) = $${\frac{{\mathtt{6}}}{{\mathtt{8}}}}{\mathtt{\,\times\,}}\left({\frac{{\mathtt{5}}}{{\mathtt{7}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{4}}}{{\mathtt{6}}}}\right) = {\frac{{\mathtt{5}}}{{\mathtt{14}}}} = {\mathtt{0.357\: \!142\: \!857\: \!142\: \!857\: \!1}}$$
