Problema Solution
A horse has 11 entries and one person owns 3 of those horses. Assuming that there are no ties, what is the probability that those three horses finish first, second and third(regardless of order)?
Answer provided by our tutors
P(three horses finish first, second and third) = 3!/11!
P(three horses finish first, second and third) = 1/(4*5*6*7*8*9*10*11)
P(three horses finish first, second and third) = 1/6652800
P(three horses finish first, second and third) = 1.5*10^(-7)
