Ten horses are numbered 1, 2, 3....10.The probability of winning of horse 1 is 1/8. The probability of winning of horse 2 is 1/7 and probability of winning of horse 3 is 1/5. What is the probability of any one of these horses to win the race? a,b,c,d,e are distinct numbers. If (75-a) (75-b) (75-c) (75-d) (75-e) =2299.
Then a+b+c+d=?
Hint(as given): 2299 is divisible by 11.
