Explanation:

We have a 5 by 3 grid of letters. There are 5*3 = 15 letters total.

Of that total, there are 5 vowels (2 'e's in row 1, 2 'e's in row 2, and 1 'e' in row 3)

So there are 15-5 = 10 consonants.

The probability of pulling out a consonant is 10/15 = 2/3

After selecting that consonant, we have 10-1 = 9 consonants left out of 15-1 = 14 letters total.

The probability of selecting a second consonant, after not replacing the first selection, is 9/14.

Multiply the two fractions found:

(2/3)*(9/14) = (2*9)/(3*14) = 18/42 = 3/7

To reduce 18/42, we divide both parts by the GCF 6, which is how we end up with 3/7.
