How do you evaluate 9P 4?
How do you evaluate 9P 4? nP r = n! (n ? r)! so 9P 4 = 9! (9 ? 4)! so 9P 4 = 9! 5! = 9 ×8 ×7 × 6 × 5! (5!)
How do you calculate 20p Rule 4?
You backed a horse at 5/1 (£10 stake) and within that race there was a 4/1 non runner, which would be 20p rule 4. It really is that simple! If you have more than one rule then add up all the rule 4's and use the total in the equation above.
