Of course, 10 * 9 * 8 is the total number of possible outcomes of the 10. A) I (5 * 4 * 3) / (10 * 9 * 
= 8.333 …%. 5 * 4 * 3 is the total possible outcomes for runners b) (3 * 2 * 1) / (10 * 9 * = 8333 …%. Since only three can be aged, and take into account the number of results of them taking different positions, this would be 3 * 2 * 1. c) 1 / (10 * 9 * = 13 888% … Not only would a higher result than is the president, along the greater the secretary, and the third is the treasurer.
