8! Ways = 40320 ways

(9!/ 1! 2! 2! 3! 1!) Ways = 15120 ways.

Number of ways to succeed: 7 x 7 x 7 = 343

Number of 5 ball groups in 21: 21C5 = 20349

Probability: 343/ 20349 = 0.0169

There are 114 = 14641 possible 4 letter words with this choice of 11 letters. There are 11C 4 = 330 different ways to choose the first two letters and then only one way to choose symmetric letters. For that reason, the probability of choosing a mirror image word is 330/ 14641 = 0.0225.
