(D) The urn contains $25$ balls numbered $1$ to $25$. An odd number is considered a 'success'. The odd numbers between $1$ and $25$ are $1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25$. There are $13$ odd numbers. Probability of success $(p)$ = $\frac{13}{25}$. Probability of failure $(q)$ = $1 - p = 1 - \frac{13}{25} = \frac{12}{25}$. We are drawing $2$ balls with replacement. Since we are only performing $2$ trials,it is impossible to get $3$ successes. Therefore,the probability of getting $3$ successes is $0$.

An urn contains $25$ balls numbered $1$ to $25$. Suppose an odd number is considered a 'success'. $2$ balls are drawn from the urn with replacement. Find the probability of getting $3$ successes.
