The game is formed such that a duck is either winning duck or a non winning duck .
there is no other result for any duck present in the game .
Also choosing a duck is a fair game it is independent of any prior situation .
here we would be using a basic probability formula , that is
Probability of a result = number of items in favour of that result divide by total number of items present in the game .
Let us start with assuming that total number of winning ducks are = x
The probability of winning a duck =
: number of winning ducks divide by total number of ducks
this gives us : 0.24 = x/ 25
0.24 times 25 = x
6= x
so there are 6 ducks are winning duck rest 25- 6 = 19 are non winning duck
the probability of not choosing a winning duck =
( total number of ducks which are non winning )/ total number of ducks
( 25- 6 ) divide by 25
19/25 = 0.76
Answer ( a)= 19
Answer (b) = 0.76
