62arrey yaar kya kar raha hai
can two horses win together?
these are not independent but exclusive events!!
62kaise priyam..
they are all exclusive
let there be n horses
probabilty of A winning is P(A), B is P(B) and so on
then
P(A)+P(B)+P(C)+....P(X)=1
Hence
P(C)+....P(X)=1 - P(A) - P(B)
Which is the probabilty of A and B not winning...
